Go Teaching Ladder
The Go Teaching Ladder is a site where you can have your own games reviewed. From their introduction:
- Several high dan players have recommended getting your own games reviewed by stronger players as a good way to make progress. However, it is not always easy to find stronger players willing to comment your games. The Go Teaching Ladder has been set up for this purpose. Volunteers in the ladder comment games made by weaker players. Anyone may submit a game for commenting by a stronger player.

The GTL is a free service, no strings attached. It has been running for over 20 years.
As of 23 March 2016, GTL no longer accepts request for new game review. The archive of reviewed game remains accessible.
(note by someone not related to GTL): for lower ranking players (single digit kyu, maybe even 1d), one alternative is to load your games into Leela and ask it for advice.
