Hey that one is a very well painted harlequin in my eyes. Like the realistic way of this whole piece. The colours are well chosen, not too powerful and that makes him somehow very harmonic... really like how the bright mask pops out of the whole piece. Great focus here - i guess if you try to get more attention on such a contrast dark/bright to set such focusing points there will be a fast improvement in your painting... Keep on happy painting!
