Artist looking for Feedback

Hey everyone, I'm trying for an apprenticeship in the next month or so (the owner said he's not making any decisions until the spring), and I was looking over my portfolio and thought that this might be the best place to post it for feedback and critisism. For what it's worth, I've been looking for apprenticeships for close to three years with no luck (Philly is extremely elitist, I've found, and while I have gotten very good ink there, they have already dashed my dreams of apprenticing there) -- this is my chance to really show my desire to be an apprentice and I know having thumbs-up artwork helps. So please, if you will, give me some feedback, where can I improve, what do you like best, what would you, as artists, like to see more of? Here's the link to my best pieces (and some of my doodles). http://fin-mieux.deviantart.com/gallery/ Thanks for your time! Morwil
