Welcome to Gaia! ::

Aww, your art looks cute~

As for critique, one of your recurring problems is getting the shoulder right I think. All three of your pieces have the shoulder on the right sagging down too much.

I redlined the first and the third pieces~


-----------------------------------
For the first piece:
- the eyes/eyepatch seemed abit misplaced. If you removed the eye patch, the two eyes would've been squished together too much, so I moved the eye and eye patch further apart and lifted the eyepatch a bit.
- I reshaped the head, so it's more round and doesn't cut in at the back
- moved the ear out and down; the ear seemed too close to the eye, and usually, the top of the ear is in line with the centre of the eye
- the shoulder as mentioned above




---------------------------------------------------
For the third piece:
- I reshaped the torso and added more width. I think torso's go in as it gets to the bend in your back, and then back out again (**please note! I forgot I was doing it for a guy, but for guys it's less shaped since they don't have womenly curves/butts XD ) you seemed to shape it so it just keeps getting thinner
- that shoulder thing
- made the segments of the arms longer. They seemed a little stumped compared to the long torso.. I wasn't sure what the arms were doing so I just left it unfinished.






But yes, you're definitely doing well~ Just keep working on anatomy. It's a hard thing for many artists (i personally make mistakes all the time!)
but I hope this is of some sort of help. ^^ 3nodding

Keep up the great work.

For the first piece, I think it would look better if you didn't individual lines for the hair; it makes it look stringy. Here's a short tutorial, but there are probably other better ones somewhere if you look- http://www.cablenet.ne.jp/~japanime/tutorial/hair1.html

Otherwise, it looks good & I can't think of anything that Cloverella hasn't said. ^.^

Hope they're a little useful. =]

First of all, keep up the good work! Your art is coming along fine!

Try to look for muscles and how they react, a pose in that position with slim/muscular guy would have at least subtle curves (possibly not as big as what I did, but you get the idea).
For a guy this tall he will still have a bit of width to him, even if he is rather slim. Try and look at the structure of the torso and the shoulders because they are broader then you think.
The face needs to come more forward, and the eyes should be lower.
I suggest you could study muscle groupings in the neck, trunk and arms as this would be very helpful.
I recommend Posemaniacs.com or if you want to get a book, Anatomy for the Artist by Jeno Barcsay is excellent.
Don't stress to much though because there are lot's of resources that can show you the different muscle groupings.

I hope this helps.
