For the most part, I use photoshop. I got a chance to try out paint tool sai, and I sort of fell in love with the ink pen-tool thingy.

Then I reached the colouring part, and quickly remembered why I stopped working with proper linearts. So I'm not comfortable with the result at all :< (though I'm a bit surprised, because I didn't expect it to end up quite as... comic-esque... in style o.o)
