Well, at the moment, I am beginning to use vectors to make wallpapers on Paint.NET. I'm still learning, and they're not as good as the wallpapers I have downloaded.
I'm drawing ponies by hand as well, and that's going quite well. They're lead pencil, and shaded in, and maybe I'll get around to scanning them. I like the grey-scale way they look, but maybe I'll start adding colour with pencils. Not paint though, I hate paint. Pain in the ass for me lol. I draw them from vectors and pictures I find on Google Images.
My main (arty) interest is music composition, and my artist name is as my online alias (DaemoN67), and I spend a lot of time doing that. I use FL Studio which I torrented, and it's a good... no, GREAT program, so I'm saving up to buy it legally.
I spend a lot of time on FIMfiction, YouTube, Equestria Daily, and until ponies came into my life, I was heavily into Minecraft. I used to frequent minecraftforum.net, but that's no longer. As of November 23rd, 2012, I haven't played it in a month. MLP kind of took over. I guess I'm also a bit of a furry as well, but that's not an interest I've acted upon; I don't really have time for another obsession.
Anyway, that's me.
I favourite any wallpaper I download as well, so getting your pictures/wallpapers into my 'favourites' folder isn't a big deal. If you get a watch from me however... that's a different story! : P
