I like where you're going with this painting and I like geometry and symmetry. Personally, I like more simple things that are not busy and this feels too busy to me. This is a personal view and others may feel different. I would take out anything 'curvy' and stick to straight lines and I would also get rid of the pink and stick to blues with just accents of the yellow and orange that would act as 'anchors'. If you want to leave some pink, I think this could work if it was in equal amounts to the yellow and orange. I don't think the painting feels 'balanced' right now. My eye is constantly drawn to the pink area and I feel that this interferes with the movement of the piece.
Anyway, that's just me!
