Welcome to Gaia! ::

I at least, use the same hands for boy and girl bodies. The real distinguisher is the torso area. Let me show you a sketch and maby that could help you...
Male Sketch
Notice how the body is more diagonal then straight down. I hope this helps^^

Thank you so much everyone X3! Sorry I didn't respond sooner x.x

Unending Shadows: I kind of understood. But what you told me really helps^^! Thanks!

Lieutenant Shotgun: Thank you X3! That also helps me! I have to practice drawing and thinking that.

Smexii Error: Thank you for the tutorial X3! It looks like it will help me =)!

With males, you want to make sure that the features are sharper. Thats the first thing. Generally speaking, men have broader shoulders, thicker necks and neck muscles, and fewer curves. They're much straighter, much blockier than women, so be careful not to make the waist too narrow or the hips to big. As stated earlier by a bunch of people, the hands and feet should be larger. The ears and nose will be slightly bigger (I think.Don't hold me to that one), but the eyes will be smaller. Men tend to have thicker eyebrows, or at least less sculpted ones, since most men don't pluck. Generally speaking, the more masculine you want a guy to look, the broader you want the shoulders and neck, and the thicker you want their limbs to be. If you want they guy to seem slight, or gangly, let the body taper of slightly.

You can find many amazing tutorials off of Devianart.

Here's how to find a lot of good ones without trying

Go to my deviantart account -->go to my favorites--> click on tutorials--> there you go, tons of tutorials that I found very useful and well done. I really need to actually do them so that my art becomes better. All I know is that you can't become good over night, it takes a lot of hard work, patience, maybe a few tears and diligence. Although I am not that great, I have seen a vast improvement of my skills over the past year and I'm sure you'll improve to.
