i like that you have a lot going on- movement wise, color wise- the purple hue has much contrast with the yellow and green "subjects' however i would try to add more demension to the piece. In addition, it seems to obvious in the grounded level so to say, because where the other background come to play is very u uni-demenionsal. i would say just work more woth the 'backgound' so the piece as a whole come together. I do like the color u have chosen, other than black and a little
own, they feel pastel to me, i would just say to go with it, add more dimension, and depth of field to it overall. It is intriguing to the eye not only through movement of composition but also through your use of color.
