based on my upcoming Shirt motive (or you can seen it about a muster, whatever),....
so ihave try this complete reedit from an jpg picture (Luna)
complete created with GIMP 2.6
The moon was complete selfmade (sitting on this 3 days long for find a good way)
Orginal Luna Artwork by: miketheuser
(it's the second variant of this pic,.... the first have nippels )
because it's only a render graphic i have no skills (or programm) for create vectors -.-
