They say that imitation is the sincerest form of flattery. I had seen a custom exactly like this one in the Critiques board a few years ago (which followed the construction scheme that Push You Down originated), and was so impressed I'd built my own.
I used flat black for a base and used a shade called 'British Crimson' for the red. Applying the red was a bit of a chore being the paint was so thick it didn't want to cooperate with my brush, though the effort was well worth it.
