I'm keen to explore the idea of having a rock there a bit more... however, I don't think it works if the climber is multi-coloured. Also, I kinda imagined the climber to hang of something, instead of 'just' scaling up a wall.
Two things I'd like to try: 1) Can you pick a different font? One that's flat and doesn't have a 3d effect 2) Take off the word 'bouldering' completely
