I like the layout. Over-all pretty nice, but I do have some crits-
I think you should make the Contact, Resume, etc. buttons bitmaps like your title button. The raw underlined text looks kinda funky on the orange background.
Your texture work looks good, but some of your portfolio pieces tend to have too much dead space in my opinion. Scale your renders up to fill in the space, so we can see more detail in the textures. I feel like your 2D art section isn't really helping you... Do you have any examples of traditional paintings you've done or anything like that?
Hope this helps!
