Yeah, I thought that it might be big enough to show enough detail to allow someone to recreate it in a bigger format. The original Panel5 is so small that it's hard to work out what is going on.
Interestingly, the picture used in the HRP has a very similar theme - ie someone getting bitten whilst being watched over by a winged creature (it's even been reversed). I don't know who did that version of panel5 originally, but maybe they knew the original panel5 source image and went for something with a similar theme?
