Reddit mentions of Cyclopedia Anatomicae: More Than 1,500 Illustrations of the Human and Animal Figure for the Artist

I like your work with the muscles in the chest and torso. You put a lot of work into defining that area, which is good because the torso is what everyone first looks at, besides the face. You're going in the right direction, however I feel certain features are perhaps too exaggerated and others aren't defined enough. Are you using a reference for your work? If you aren't, you should. I think that's one of the most helpful things you can do while modeling, especially when you're just starting out. If you are, try to look more carefully at the forms you're seeing. Also, as long as you're modeling human figures, you should learn a little about human anatomy. Specifically, you should learn about muscles and the shapes that they form and it really helps to actually learn their names and be able to identify them. It's something that I'm trying to do with my own work and probably the majority of professional character artists will profess an intense familiarity with the subject, so if you intend on continuing work into character modeling, you should eventually brush up on it.

I'm nowhere near home right now, so unfortunately I can't give you the name of the anatomy book I like to use 'cause I can't remember it. (EDIT: Now I remember, it's Cyclopedia Anatomicae.)For now, I can give you a link to a very, very basic guide to male anatomy that I have saved. It's not perfect and it's aimed at 2D artists who aren't drawing characters in A or T poses, but being able to get a handle of human form will be good for you. It'll help you iron out some of the other areas you need to concentrate on, such as the proportions of the hands and feet, and the definition of muscles in the arms and legs. Here's the link.

This one is a link to copy of a figure drawing book by Andrew Loomis, and it is a bit more refined and involved and is again, aimed primarily at 2D artists. But don't discount being able to draw human figures. It will help you. Here's the link..

The important thing here is to practice, practice, practice. Keep modeling as much as you can. Remember that it takes 10,000 hours of good, honest practice to become an expert on something. I think this model shows you have potential and I would like to see more from you.

One last thing, was this character modeled so it can be animated? If so, post a complementary image with the model's wireframe turned on. That way, we can help you with your edge looping.
