Hi, here is my roundbrush attempt for this study, it is a fun challange, for color there is mostely red, oranges, yellow and violets used, with diffrent level of gray. To confidentely paint a portrait with any tool I would suggest diving deeper into head construction, being able to understand how planes of the head are positioned and react to light will make it much easier to paint. There are some lessons on that exact topic here on ArtWod. Keep up the good work! | Artwod Feedback
