Something about this smile and twinkle in her eye seems slightly characterized. I'm not sure if that's what was intended or if this lady has the remarkable good luck of actually looking slightly cartoony in real life. Either way, this is delightful!
I always see your paintings and go "This is an indication of an artist who's in tune with his strokes" why? the background feels apart of the figure and each individual stroke on the face or hair flow into each other. Excellent Highlights here!
