Gargoyle goes psychedelic WIP

I was looking through a sketchbook, and came across a gargoyle I'd drawn a couple of weeks back and decided instead of putting him on rock texture I'd give him a bit of a psychedelic background, perhaps as a result of 'acid' rain!

Rotring pens on off-white cartridge paper.

The gargoyle is 9" or 22cm from nasty lower fangs to tail-tip.
