I'm working on my first soldier textures completely from scratch and double their original size. I just got photoshop cs5 for free from my school, so i'm still kind of learning it...
So far I only have the arms and hands finished, of which I have renders of for you guys...
Grant me yer feedbacks!
For the 1P textures I wouldn't bother doubling there size. I have recently had a go at similar stuff and the 1P UV's can support enough detail at the current size.
looks good, a relief to see you're going further than mw2-style spetsnaz
It looks a bit clean though, you might want to shade the texture abit, give it some faded colours, especially the green.
