I like 3 variations! But at some u used to many colors mate! I think a limit of max 3 colors is enough! Even better 2! Cause is to croweded, and it should not overshine the artwork itself! That's why Rosemon was a better choice then Plutomon, more background visible. In few hours I will be home and I will PM you Rosemon artwork already cleaned.
I like the second one or 5th one kinda alike or the second to last from the small onces!
