Grotto

I had a dream a while ago where I was trapped in a lime green underwater cave. For some reason, I had a collar around my neck, attached to a rope, which kept me from swimming away. The rope itself was held tight to a rock with a little piano-like instrument on it. I was afraid of getting a headache, hitting the top of the cave like that.

So sketchy. Wanted to get the gist of it. Pencil, scanned, painted in oC 1.1 and some Photoshop.
