Your site is pretty good in my opinion - some great illustration integration. The only gripe I have is that, atleast on my computer/monitor, your site loads with no work on screen (without scrolling down). To make matters worse, you have what seems to be tabs that don't work!! Other than that, it's very clean and nice.
I'd maybe think about moving some of your info around.
Your work pops fairly well in your thumbnails, but I'd say, overall, it seems underworked or unfinished. You have a good grasp of many concepts, but I'd think about pushing them further. A great way too keep in shape is to constantly compare your work to the best here!
Best of luck!
** Oh, and there are some pretty bad grammatical problems (English), so I'd consider having a friend proof-reading that!
