Unless you were going to refine it.
Use the lasso tool to select the parts of the image and paint with color on new layers. If using this as a lighting and shading reference it is best to keep layers separated that way (lighting layers, base color layer, shadow layers)
Yeah the drawing was initially a face value study sketch so i did spend more time on the face. Then i eventually added a body. But okay, i'll definitely have to improve in making my paintings smoother than if i plan to add color as you've said.
Thanks alot! very good information, i'll either continue this or attempt another sketch very soon
