I think your current avatar (at least to me) is a decent example of something more on the western or masculine side because of the darker colors/black, the body proportions feel right, and the style of clothing is something I could see a man around my area wearing.
As much as I am happy all items on Gaia work on both gender bases, I think at the same time, if items were locked to only male bases, it would have forced the artists to think of something more masculine specific, instead of just tweaking a female clothing item to work on a male body. I browsed tektek to make a male avatar and most of the items I clicked on at first were female items that can fit on a male base, or frilly elegant "pirate shirt" like items. Or I find decent tops or ok bottoms.. but none of them really match each other. A lot of the leg mods and pants make the male bodies look really out of proportion. Most of the eyes and faces are too girly, overly stylized, or very expensive. Most of the hair are multicolored or very fancy, stylized, wispy, emo, or anime.
If you were just a typical American male and wanted to dress like yourself in real life.. I'm not really coming across much potential here and this is the best I could come up with within a few minutes of looking through some items quickly.
I agree about the facial hair and the chibi proportions. The problem I kept coming to often was that the face was just too boyish so it was harder to make a rugged looking guy or anyone in their mid 20's+ and that I was weary of sleeveless outfits on the chibi form as it looked more bishi again.
I also agree with Fire 0ak about that Summer Camp item. I like muscles, too but that one really isn't good at all.
I'm gonna be lazy (because I really don't wanna go search and upload a bunch of photos on Photobucket), but some game guys that come to mind are the main character from Deus Ex Human Revolution, Francis from Left 4 Dead. I like your Crysis 2 example but the Metal Gear guy comes off more Bishi to me. Commander Shepard comes off good to me. Halo Spartans. Any Star Wars characters. Gears of War (though their muscles are extreme, I do like their armor). I do really like Leon's outfits in your examples. The Armor examples you gave are a bit too overly stylized for my liking, as I'm thinking of stuff more towards The Elder Scrolls.
They're all good though and not seen much on Gaia so I'd be cool with any examples everyone is providing.
I think we could use some really good body mods, though that work with other items and the leg mods need to stop having the crotch come up so high on the male body. The Saint Ciel and Rosa items had no problems making the legs extend down to the limits of the avatar border, so I dunno why to make longer legs for the guys, they gotta come up into the stomach as if the guy got hit in the nuts by a wrecking ball.
(He aint ever having children).
(Where did your crotch go?)
Hmmm, some of the problem does lie with the fact that many items are designed for the female base, and that very little is done to shape it a bit more on the masculine side. However, I do also understand that it's difficult for a Gaia artist as well, as back in the day those with male avatars (some at least) specifically requested that the female mod item remain the same for cross-dressing purposes. That's why we have a lot of more feminine male version side of items. Mainly, it seems to be that people are wanting an item to be designed for the male base then converted to the fem side for a change. Again, it's about balance. I still think that the balance is about right now. It is just a game of waiting for your kind of item to be released.
Why thank you for saying as much, although I do feel this one is masculine it's not the bara that people seem to be asking for, unfortunately uber macho is a pretty niche audience. I think that if people really want it, they'll have to get a petition going to prove that it isn't a tiny proportion of Gaia.
Male leg mods are pretty variable and generally are made for more cartooned avatars, or stylised ones. I don't think there's a serious male leg mod out there. In fact, the reason I use this base is because the proportions are less rounded and chibi. There's definitely a market for general male mods if nothing else. I always have difficulty in making this avatar macho but I'm happy with a general masculinity personally, so I'm not surprised you had some difficulty finding items that went together! Conversely, I've found it easy to make a lady of myself with the items in my inventory alone! XD
As for facial hair I have to agree, no matter what you do thebase is still very youthful and rounded, the only things you can do to make it less so is to cover as much of the head and side of face with accessories like head gear! I think facial hair would look jarring in contrast to the boy face in most cases. Though, if they ever pull it off I wouldn't mind, in fact I'd applaud the feat!
