It's going to be really hard to decide without seeing them in the game. I think they both need some more black shading between the scales to bring the details out more. Side by side, that red one really pops. The red may stand out better against all the gold pile moldings, and the lit eyes might stand out more on the red.
I'm undecided at the moment, but leaning towards the red one. Good thing this topic will be endlessly debated for the next week.
