This feild of Art is So competetive its not even realistic.
You have to be the best of the best to be successfull. The hardest skill to master is taking criticism. If you can take criticism, and use it to your advantage, it can only help you. Insulting people, or their criticisms will only hinder your ability as an artist. Because art is all about how people perceive your work, not how you intended it.
Growler, you do well with taking crits sometimes, but you are ferociously arrogant and its not a good thing. Take tek's advice, hes a great at what he does.
I believe compliments of improvement are healthy, and growler you have made alot of improvements. I remember when you started you were horrific. You have made aloot of progress, But dont let it go to your head, you still have alot to learn.
The head doest really look like tien imo its just a bald guy with no jawline atm, you have a good deal of slack with the poly flow you have, you should play with it some to work that jaw line in, as for the body, right now its pretty bubbly, a good base to work from, you have the general flow down, some areas just need to be shaped alot more
