I free handedly painted this, no sketched out-line, just paint on paper.
The best thing about not having sketched the out line first is that I didn't have to 'clean' up the image in Photoshop so this is as real as it gets.
The worst thing about doing it free hand, you have much less control over how the image will finally look.
But hey, it's good to be spontaneous from time to time!!
