8x10 Illustrations

We had to take two illustrations we had already created and RE-DO them at an 8x10 size. I still feel like I have no idea what I am doing? I'm having a hard time being consistent throughout the entire illustration. Depending on what I am drawing, I have a tendency to want to render it differently. Right now my style is somewhere between realistic and graphic.....I don't know how to fully commit to one. I like how the image of my bed and bookshelf turned out but I feel like the image of myself is all over the place.

PLEASE GIVE ME FEEDBACK!
