Art isn't limited to just the people who draw, of course. You can do a lot with just photoshop filters and an imagination. While I'll admit this is no Mona Lisa, it's better than most edits and recolors I see. I'm not wild about the image by itself, but I do really like the way you've incorporated it and other assets into your signature.
Here's the original image, btw. Hotlinking to stuff on Creative Uncut usually never works out well.
