Mischievous pixies

I couldn't have been more happy when i discovered the theme for this new contest! I had almost too many ideas so i tried to think about what design i'd like to have on a t-shirt but also what would appeal equally to men and women.
I finally set my mind on pixies but didn't only want to draw something and then put it on a t shirt. Pixies are often described as mischievous creatures that like to play tricks on people but can also sometimes be helpful so i had the idea of this design where you never really know if the pixies are stealing from the pocket or putting the coins in.
