C4rdisterYou did?! Please do. I'm new to graphics design and photo editing so any criticism is helpful
Here's some feedback, my brain is kinda fried right now so it's a bit short:
- Keep the usage of logos minimal, use elements from the logo's color/shape to design elements of the skin. Once viewed at a distance there is a lot of noise from the amount of detail that blends together. An example is in Ascent's skin for the Demoman, there is the 'peak' from Ascent's logo on his chest and then the Ascent logo and text below that, and he has the logo+text on his arms and back. The Froyo skins for the Soldier and Demo actually do a good job of using design elements. I understand the placement of player names and I think that's pretty sick, but just keep in mind that it adds a lot of extra visual noise.
- Sort of related above but a good thing to keep in mind is layering a lot of detail on top of each other. Pretty much every class has their shirt/jacket, and then some sort of straps that visually divide the torso in some way, either diagonally or vertically, I think you've done a good job about keeping those parts contrasting. Like on the back of Scout's jersey there is the Froyo logo on his back and then the logo again on his pack. Here's the back of the i58 skins for reference: http://i.imgur.com/hGH5Khg.png
- Avoid straight up black or white or very bright colors, the color palette of the natural TF2 world down to the colors of the maps is slightly subdued and lower saturation. Using an off-white or a grey-ish black helps it feel more natural for the viewer. This is more of a personal taste thing (and it might be just from the screenshots), but I like to retain a good amount of the original TF2 texture, especially their reds/blues.
