me thinks you should change "Home Page" to "Andrew Dyksterhouse Portfolio" or something along those lines. If I were to bookmark your site, it'd just say "Home Page" in my bookmark menu and I'd probably not look at it again.
as for your demo reel, the lighting on your textured gargoyle is not so great. I can't see nothin
Perhaps do 100% self illumination if it's just diffuse, or go ahead and throw some more lights in there. I'd say the lighting on all the toons could use some work. Maybe you can render them in a game engine. Unreal, Quake 4, Crysis, any of those could work. Marmoset Toolbag is floatin around PC somewhere for free.
I'd like to see more of that rifle from the Manhattan Project, personally I think it's your strongest piece (The cheshire cat aint too bad)
Show it from a FPS point of view and textured. I'm assuming it was for a mod though and you were probably just in charge of modeling it. MOAR!
Show some flats and sizes of your textures; that's always a plus. Others will be able to gauge rather or not you used texture space efficiently and offer some help in that area.
I'm not so fond of the "Services" tab, that could be replaced with Resume or something along those lines. But then again, just a personal suggestion. IT'S YOUR TIME TO SHINE!
You got some works to do my friend, but I'm sure you'll find all the help you need here. You gotta follow through though!
