I would say that this is a fantastic venom design. It's clever, it's creative but it's faithful to the comics! I like all different kinds of Venom weather it be a more body builder style Venom like you've done here, or the more hulkish Venom!
why is his mouth pointed? it looks like a beak... and the inside of his mouth seems like there is no throat or anywhere for a tongue to be... sorry for those negative thoughts, anyways here are the pros... the body looks awesome! I love how the eyes look... I have never used Zbrush is it good?
