I think 33 colors is too many... I don't mind a lot of colors when necessary but this probably doesn't benefit from the extra colors! Also, the preview is not appealing at all!! It doesn't do this justice and might be keeping people from clicking!
I think it's funny how the piece doesn't look at all like the reference. Nice work on this, though.
