I see, thanks for your suggestion. I try figure it out.

While I like this piece, I'm afraid it won't be accepted for now as you've used the spray paint tool a lot with little clean up. For example, if you refine the part of the animal that's surfaced and the edge of the water, that will already make a significant difference!

Don't let this discourage you! I'm looking forward to adding this piece to the gallery very soon
