How/where can I get comments from strong players on my gameplay?
GoKibitz is a new website that offers a nice frontend for discussing games. I did not use it myself, but it looks promising.
I have no experience how strong the players are which are commenting regularly, however I saw at least many 1d or 2d comments.

If you are willing to spend money on getting regular full reviews on your games I can highly recommend In-seong's Yunguseng Dojang. It is available for American and European timezone. You are getting lessons and reviews of league matches from high amateur dan players. I participated in the school myself for 1 year.



As I am new to this site I am not sure if such an advertisement is considered good practice here. Please comment if it isn't. I am not completely sure if the question already is a good fit for the site, because there can be very many answers providing different resources. Selecting one of them as the one right answer is probably not possible.
