Now here's a small bit about the textures, mostly the bump map. This character is meant to be really old and have lots and lots of wrinkles.
In the final version he's not as old looking as I would of liked. I did model him with the intention of taking him in to zbrush and adding a lot of details like lumps and bumps and wrinkles then making a displacement map from it for the lower res version. But after testing I just don't have the memory or using the right renderer to achieve this.
Anyway for starters on the bump map, the textures for just his face were 4096 by 4096, which was reduced to 3072 by 3072 for the final texture. I first painted the above map in Deeppaint 3d. I just quickly painted lots of lines that I wanted my wrinkles to run, so its easier for me to paint when I open this texture in photoshop.
Now here's that texture opened in photoshop I've put a 50% gray layer on top of it and turned the opacity down a bit so I can see the texture I painted in deeppaint , I will be painting on the gray layer using colour dodge and colour burn
using colour dodge I've started painting lots of wrinkles following the lines of the layer underneath
using colour burn as well now
sorry but I've moved along quite a bit now this is now the almost finished bump map some different layers have been added. Some spot layers also some layers with very fine wrinkles
here's some bump map tests, some displacement was used in these pics. For the final version I just used normal bump mapping
