^^ Thank you for the warm welcome! Digital art is kind of a broad spectrum and can cover all of those things you mentioned and more. Mostly, I do digital painting, which is the same as painting with a real medium, but it lacks the mess (I'm very OCD about messy things). Here is my current work in progress.

I like Maya (I use Anime Studio sometimes) and I'm partial to Gimp. 3D isn't really my specialty, but I've tried things like Blender before.
