the Rules you can find here: http://www.planearium.de/sp-studio/forum/viewtopic.php?f=2&t=143
(forum-> anouncements-> contest)
but I copied them here for you: RULES:
•The picture must be created at sp-studio.de and submitted here till April 15th, 11:59 PM (GMT+1).
•No editing with additional software!
No effects, color change, zooming, rotating. Just SP-Studio pictures.
•Add a fitting English title & description (optional). You can link to reference pictures. No text like "VOTE!!!".
•If you upload more than one picture for a contest the newest counts and the others are deleted.
•When the voting starts registered users can rate the pictures (1-5 stars) till April 30th.
•Vote fair! Don't manipulate results by telling friends to give you 5 stars and others 1 star or you will be banned.
And about the things you have seen at other users pictures:
You can, for example build a second head out of hair highlights or free-style shirts + a hairstyle.
If you want to know more, you can write me a PM or ask anybody around here.
