How do I politely remind a professor to respond to my request for feedback
After two weeks, you're within your rights to send a very polite reminder to the professor to have a look over your stuff. 

However, I wouldn't make the subject title 'kind reminder'. Be efficient and help them out, make your title 'MSc Literature Survey' or something to that effect.

As for including when you were last in contact with them in the body of the text, I would leave that out. It might just be me but it comes over as a little passive aggressive. If you're wanting someone to help you out, best not to rub them up the wrong way before they've even started.
