I decided to retexture the beggar in order to push his style a bit more as I wasn't happy with the previous texturing. Below are some colour variations and combinations, using neutral colours seemed to be the right choice to keep things "minimalistic" and let the other elements stand out such as the lines and overall design.
3, 5 & 6 seem to stand out for me, in terms of variety of colours and unity. However 3 might be a bit too dull. Any feedback is welcome.
