I'm definitely a fan of anything with a shell. In the process of restructuring how I want to present my drawings, tackling painting is high up on my priorities list. I have a long way to go, but here's a step!
If anyone's interested, the steps I took are below!
In the last phase along with modifying the mushroom, I decided it would look better if I made the lights in said fog... look more foggy. I also sharpened a bunch of highlights, added a few shadows and finished up the barnacles on the right side.
As a whole I have no idea how I eventually want to stylize my paintings, I think ultimately I should probably take some painting classes to really learn the basics. There are so many cool styles out there, and a lot of fun ways I see people painting (ie speed painting). So I'll probably look into doing that in the future.
