Dear Sir,
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

Hi,

I have submitted several revisions you have asked. I looks like you have again extended the deadline. Should I withdraw my design and submit another. It seems you are not happy with my design.

Thank you

Hello,
Could you give me feedback on the revisions I made to you?
Thank you.

Having a meeting today with staff to go through the designs....I just extended the dealine because time was otherwise running out before I could have this meeting.  Will give feedback/eliminate as needed soon!
