Acrylic transfer

This is my first attempt at a acrylic transfer print, for this i placed the original black and white picture on a white card, then i pained over it with red,green and yellow paints, then i left it to dry, after that i got a pot of water and gently rubbed my fingers over the original picture until the card was left. This process has given the picture an abstract colour to it.
Next time I need to be more careful when erasing the picture as you see that i have rubbed away some areas to much.
