PJ has different themes that people use, some offer lighter backgrounds.
The PJ rules state that solid backgrounds should be left transparent whenever possible. If this piece is meant for a specific colour background, then perhaps you should do something with it, make it an actual background.
Thanks! Why no transperant - I found original PJ background color too dark, IMHO...
Very cool! Nice use of straight lines.
The grey background seems unnecessary though, why not leave it transparent?
