Hello contest holder,
I just want to tell you that if you leave your project non-guaranteed, you will not get the maximum talent for your budget. Smart, professional and talented designers all go for guaranteed projects and they all give maximum effort and commitment for a guaranteed project - knowing that the project is worth their time and effort. Most talented designers avoid non committment projects because they know in the end, the client is not committed to project, will not give them feedback to improve their designs and eventually, they will most likely get a refund. Real talent comes when you guarantee your project. Trust me the designers you know that your project is one of their strengths will flock and commit to your project. So please consider this message,

Also, Your budget is small for this project,
thank you

Just to clarify, you want one illustration that contains most of the elements in your list?

Yes.

Hello - The project sounds interesting but the payment is far too low and not even guaranteed. Please consider both, thanks!

Hi Everyone,
The project is now guaranteed payment. Please have fun and let your imagination fly!
We also extend the deadline so please try to take your time and work on it.

Looking forward to see all your great works!

Could you provide feedback please?
