Possible feedback on my entry would be much appreciated.
thanks.  

Thank you very much for your very poor rating. One star will motivate me to work better. Please wait for my next design. I am working on it.

Hello sir,
Please provide your valuable feedback for my designs.
As you can understand no project can be successful without timely feedback & continuous interaction, thus we request you to provide your feedback.
Waiting for your feedback
Thank you

Dear Sir,
Please don't 1 & a 2-star rating, this damages our public profile, simply 3 stars or eliminates the design that you don't like.
Thanks a lot.
