Echinoidea #4

I've been working on a commissioned piece for the last couple of weeks so haven't been able to progress my Sea Urchin print until this morning. This is the first proof of the first colour layer (which is a blended roll left to right).  The proof has revealed some areas (top left corner) where the etching acid hasn't bitten into the surface sufficiently so I'm going to try to re-etch that area before printing again.
