I like the color from your paint sticks. I got some but have not created a piece using them yet. About your background - it is fine. Move on to your next piece. I work in a series so I can try different things in each piece. I pick out one thing I really like and one thing I want to change. You could get a piece of clear plastic to lay over the dancing ladies and use dry erase markers to play with other possible background designs. Have fun.
