This was made ages ago by me, on Microsoft Paint. I just mainly used the pencil tool and that's it and filling with colors. I think what I most liked about it is the hair how it turned out. And to be honest, I wish I can draw like this on MSPaint again. It would be a lot more easier using a tablet. Last to say, this is a character from a comic I used to read called Homestuck.
