Dear Project owner,

I have submitted my designs.
I know you are busy but, would you mind to give me your feedback?
Please tell me if I am on the right track.

Thank you!

Best regards,
Coco

Dear Project Owner.

I apologise for my boldness.
Are you going to choose a winner on this project or at least eliminate designs you don't like.
Designers prefer to know where they stand.

Best wishes!
Coco
