I can occasionally do a good job with fingers but it's heavily dependent on angle and this is a terrible angle as far as good fingers are concerned because I cannot foreshorten at the best of times even with bases XD

My sister is one of those people, but I have watched her draw (we always miss the days when we used to sit next to each other) and she doesn't always do it in one stroke XD

The tattoos will actually appear on three characters, this one is Zara, she pops up a fair bit (if you've missed previous pics) as she's a major character :)
