The repetitive text was mainly the bits about radiosity and baking on the low poly page and the descriptions of each piece being made with 3d max, photoshop, blabla. I think the CV is sufficient enough to explain the programs you use and you don't need to say it for each piece.
I could be wrong on that though, just my personal preference
One thing that is missing from all your images except the UC/level design ones is contact details. I suggest using the same template as you did for the UC pieces for all the other images to keep a consistent look. Personally I prefer the single bottom opaque bar of the UC ones than the double black bars of the level design ones at the top/bottom.
Keep the black border, I like it :p
Another thing I like is for "thumbnails" to be the same width. It looks tidier. For something like the tractor, you could do with a render of it's back perspective to extend the image, width-wise.
Won't be hard to make that UC texture sheet the same width as well.
For the mobile textures you could put the vehicle texture on the same image as the vehicles, and the buildings for the buildings.
You should also re-do how you laid out the level at the top... 3d max Viewport images look kind of unprofessional with all that perspective window text on the top left.
I can barely tell the difference between the top view and the one in the bottom left. The middle one is quite samey too. There's definitely a better way to present all of this.
And you could use some tri count/wireframes for the props in the dungeon page.
