Hello Fuentes! You already have great painting skills in my opinion. If you want to improve, below are my suggestions:
- I think you can soften some transitions, especially about the green tones of the cloth. Maybe you can try to add some diluted layers of intermediate color between light and shadow areas.
- you could try to add more color variations on skin tones, like cool and hot color to reinforce the contrasts with light glazes. Face and hands are appropriate areas to receive more saturated colors, in order to captivate the eye. Take a look at SaintToad's wip, it will illustrate the point.
- The texture effect on the ochre-coloured cloth looks really nice, I think you can bring it on the shaded area and softer transitions in the same time.
Well, this is my view, for what it's worth. Anyway, keep up the good work!
