Here is my conch! I found this really challenging to draw, especially observationally. I think a few of the high points are making it look like eyes on a sea monster! I love working in charcoal and find it really hard to access good content on how to use the supplies. Happy to have discovered this class, thank you! 

I mostly used willow charcoal, white charcoal and a compressed charcoal (medium), along with a kneaded eraser.
