I'm not much of an expert on anything, but I'll offer what I have.
Blaidd:
I've been in a variety of art classes and several art clubs, and I'm also self taught in a lot of areas, so I can help you out in just about anything that has to do with traditional art. Anything from simple drawing and sketching, to painting (acrylic, watercolor, oil paints), to even sculpting. Iv'e also been in a few digital media and commercial art classes, so I know a bit about that if anyone needs any help.
Besides art, I'm also a bit of a writer. I've edited a lot of stories in my time, and I know quite a lot about story outlining, character design and development, sentence structure and flow, vocabulary, and just about anything that has to do with writing stories.
I have been in two psychology classes, am currently in an AP psychology class, and am going into sociology. If you need help with understanding a part of the human brain, want to know who Freud was and/or what he did, or would like to understand why people do some of the things they do, I do have knowledge in this area.
As a side note, I also study philosophy in my own time, so I might be able to chip in on a thing or two about that.
Also, I'm a bit of a cartoon enthusiast and animation buff. I don't know if that kind of information is helpful to anyone, but I'm offering what I got.
Lat but not least, I dabble in a little bit of photography. Another thing to consider.
