Figuring out body language is interesting, it helps to look at examples of real life animals to egt an idea of what to do. I intend to have my stories as comics, so it's extra important that I figure that out! Designing them is a blast too, I put a lot of time into each of my character's designs (and redesigns!).
I enjoy how people go out of their way to comment on people's works, even if the piece isn't a part of their niche interests. It's not too uncommon for me to get into a casual conversation when I didn't expect it, which I really enjoy. On other sites I'm on, comments are very seldom, which I find disheartening. Further, I haven't had bad encounters with people on here, it's been positive and friendly, rather than on my toes.
