I like the more dark environment although I have to agree with m1kclark about the weird shadows, they seem to come from the light above his head. I would experiment with a rim light to add a little more drama which seems fitting to the environment/situation heΓ’EUTMs in.
The texture seems correct but in my opinion is a bit to blurry and lacks definition compared to the environment.
Also, try to avoid twinning: the 4 legs/arms in the picture seem to be in the same position. Having them in slightly different position will make the image more interesting.
Seeing a finished version would be great, keep up the good work.
Ps: the lamp on the left is really clean, like its new :p
