Hi Kojisan, welcome to CA

before you worry about the colour you need to get your drawing in better shape. It would be best to try and get a photo ref in the pose you want (or use yourself in the mirror) and fix up the anatomical errors before you procede.

For example you have made his left forearm much longer than his right.
His shoulders are too narrow. hands don't look like that and his legs are the wrong length and thickness.
Get your basics down a little better and study anatomy and you'll be coming along fine.
