Medusa -WIP- Picture

The third idea for my graphics project. It's not quite as much of a 'traditional' Art Nouveau design - it's a little more inspired by the psychedelic revival of nouvea in the early 70s. I'm still not quite sure on the colour scheme that I should use; so any ideas would be appreciated!
*I had to scan this one in two pieces, so if it looks a bit funny down the middle - that's probably why!

**it looks much better in full view!
