good advice given already - I agree about that white. It's too much and to samey and right in the middle, dominating the painting.
I like the natural colours and swirls and shapes and textures - a soft cream might work better with only a very little amount of white and a little more thought into what is going on in the middle - don't forget quiet areas to offset busy areas.
It has a lot of interesting things going on and potentially a really nice muted colour range - if you work through cool and warm neutrals and fix that too large white area it could be very good.
hope this is some help.
