It's all abstract, and made from scratch with paint.net. I only "draw" occasionally (industrialism was made out of a scribble), I use distortion effects like dents to get me the shapes I want.
I have a deviantart account here: http://xhin.deviantart.com/ Until I get these hosted on my site, I'm using direct links from there, which occasionally break.
I only use a few tools (no plugins so far), but I've discovered hundreds of techniques on how to use them. I'm separating "generations" by points where I learned and practiced a bunch of new techniques at once.
