Sorry for the late response, and thanks for the comments.
@felipefrango - Cheers for the reminder, knew I'd forgot something. As far as the leather goes, I struggled intially as well, in order to get a painterly style it seemed to require painting over-exaggerated cracked leather due to boiled leather being quite plain. In the end I used worn leather reference images, ran some levels through it to get the right balance for overlay, with additional over painting to push the edges. I'd say I prefer how the boot leather turned out in comparison to the main leather bits, I spent a bit longer getting the colour from concept and played with some extra filters. My first try texturing leather though, so I've got a few ideas for future attempts
Here's the Diffuse, Specular Level/Colour, Normals. I had a Spec Power/Gloss for the little 256 texture for the cigar and goggles, but I ran a few nodes through the material in Unreal for the main body's Gloss map, certainly not a proper solution, just a last minute placeholder that I forgot to replace.
Crits on the texture work would be really appreciated, always the area I find the most demanding and it's not the neatest texture ever.
