Done for a contest on dA - http://tilwen.deviantart.com/#/d435oqv - we had to draw something based around some pre-composed lines (in this case, the thumb and palm lines and the topmost bubble. A scribble, so to speak). I picked up my stylus - i am trying to use my Tablet more and more lately - and this happy mer appeared.
She does bear a resemblance to Ariel in her posing but i can assure you it was unintentional. the positioning of the hands dictated the arms, then the torso and so on. I know i haven't been around lately but life is busy busy at the moment. I do have a load of pics waiting to be coloured, so bear with me!
