Hi Ross, I hope you don't mind me re-posting this in the thread. I enjoy the vibrant color in this.
One thing I wonder about is those little bits of white line in your black outline. Were these intentional or did they just happen when selecting things? Since it's not clear if they were accidental or not, I would say either paint them out or enhance them. They have a definite relationship with the textured leaves. The textured leaves against the large flat areas of blue and pink are what give the piece some depth in space. If you have these white bits of line, just be aware how they affect this depth.
