How do I show you my design?

Hi Saif! Im not sure since your design hasn't appeared on our project. You do not see a submit button on the project? Are you able to send it in a message? Thank you,

No, I can't send in comment section,Please send me an invitation i hope this will sort out everything OR contact support please.
Thanks.

I have now invited you

Bingo, I already submit my design, If possible please send me the private feedback.

Hello CH,
Thanks for the invite...but it was short notice, I only have under 1 hour left to submit.
Can this contest be extended for us to upload our entry? Thanks!

Thanks for the extension CH, please add feedback for now on where to improve the design...
Please don't rate 1-3 stars coz it will only greatly affected our star rating here...just eliminate it if it doesn't have potential or if you do not like the design. Thanks...I hope you understand!

Waiting for your feedback, If you want some changes or want new direction Please let me know.
Thanks.
