Since your website`s purpose is to house your work, i hope you don`t mind me critiquing those.
But, from a fellow graphic artist/photoshoper/3d artist, your samples need to be self-critiqued more harshly. A portfolio should represent the top tier of a persons` work, and i see a mixture of quality levels in your samples. For your logo`s some of them have nice designs, others have bland ones. Some have excellent color choices, some ignore basic color theory and contrast. For your 3d, most of your examples should not be there t be brutally honest. The abstract ones seems to work well, but you often don`t mind your material repetition. Others are too simplistic and can be done in a matter of minutes, which completion time does not matter if its presented well and intriquing to the eye (som eof the best designs are quite simple) but you seem to be lacking in presentation for the 3d stuff as well. 3D means you caqn view things from multiple angles, you should attempt to make use of that more. And lastly, you seem to be lacking heavily (no offense meant) on textures and/or materials. You seem to have the basics down, but that won`t suffice for most things. If you`re interested i have a texturing guide to help new video game artists, but it should work well enough for prerendered 3d as well:Texturing Guide
Both your 3d and logo work should be minimized imo to show only your best, this will help sell your stuff better.
As for the site, i actually like the colors, as you can tell with my site i feel white on black is the way to go
However, its layout does feel a tad template-ish. If you made it yourself i`d recommend mixing the design up a bit, perhaps even implementing some of your graphics into it, in a nice clean manner.
