What will be the printing technique? Do you need vector, separate colors?

I'm not sure. I think we will need scalable quality which to me sounds like vector.

Hello, sir! U hv told us to make 4 tennis pose... Now l'm sending u 1...if u'll like it then l'll do rest of 3

Hello contest holder, would you mind to change your project become guaranteed project?
I really interestesd with your illustration project, If you don't mind you could check my works on instagram @enyessst. If this project is not guaranteed, I'm affraid If in the end, the client is not committed to project, or will not give feedback to improve their designs and eventually, will get a refund.
Please consider this message,

Thank you
Anindy

Thanks! I will think about it. I agree it might help get more designs. I understand what you mean. Kris

Thanks. Very good sumo so you're looking good.

how about my submitted design, any feedback?, oh yeah its not guaranteed project

I extended the deadline and made the fee certain. So if you are still interested you can work on it! Would love to find my tennis sumo!
