you really need to work on anatomy. You need to use this site. http://www.posemaniacs.com/blog/
use the 30 second drawing every day and loosen up. The move on to the random poses. it will help your work. post your results please.
yup! it’s awesome. I fill like 2-3 pages of the 30 second drawings then do some of the random pose ones, and you can really tell the difference after a while. it’s good practice and good fun.
just be careful with sharing your artworks through different URLs. i did that once. it wasnt pretty. keep it up though. as long as your shit isnt also posted on DeviantArt, its ok.
