serfr invites us to to create abstracts from scribbles!!
Make a large thin-line scribble with the pen tool on a separate layer
On other layers, use any tool to add to the scribble to make interesting art from it. You may alter the scribble to make the final art "work" but not too much!
The original scribble must still be recognizable in the final art.
Post your original scribble in the WIP (Work in progress)
No image loads, make it all in SketchClub
Your compo entry should be an original creation. References are okay but you must mix multiple references to create something new. Close reproductions are not allowed unless it is own your own personal photo.
