It seems somehow you change his undershirt to be a regular button-up :P I think you can add more seams to the hems of the pants, and probably the jacket too.
Alrighty, my high poly is done, last update on it with the hair planes so I'll stop spamming you with pictures :P Hair were quite tough to do as I haven't done it before. I am happy with them for now, but I may add/remove cards when the artpiece is done.
@renato.medeiros As I mentioned before, the materials and colors aren't reading quite the same as the concept. There is far too much wear or on the yellow painted areas, the color (other than the yellow) should be more blue and de-saturated overall. You also have far too much shine on a material that should be closer to carbon fiber and with the rest of the textures, it seems like some areas should be rubber-like and more flexible and other more metallic and rigid, however both of those are similar in color.I also noticed as I was doing the paint-over that a large number of the shapes aren't following the concept correctly and some areas are missing, like the toes. Don't hesitate to slow down on the creation of the model, you have another month, and beyond if you choose, to work on this. The extra time could be helpful to adjust some of the proportions and details, poly modeling them in max, maya or modo if you have to, in order to get a nice clean look.
@DanaosC You're not using PBR for the hairs ?
DanaosC damn i really really like how your shoes look, quality and all! But i think you need to work a bit on your hands, i think the fingernails are the problem (maybe a tad bit too big? otherwise it's their texture). The eyes look quite unnatural to me, too, maybe turn the saturation on the eyecolor a bit down? I know he has cyborg eyes, but i would try it out either way and see what feels right.
