Sketch-a-day Challenge: Day 5

Hi,

Here's a WIP of an illustration I did (am doing?) for my illustration methods class.  It was way too choppy when I brought it in last week, so I'm trying to deepen the colors and unify the different objects so that it doesn't look like teeny chopped-up separated little shapes.

It features researchers exploring a cave with geothermal springs and strange plant life that undergoes chemosynthesis instead of photosynthesis.  I'll probably explain more about what's going on in it when I'm done.

Bad quality pic by the way-- my scanner's not working so I had to take a digital photo.

:-(
