Great! Nice set up.
Just looking at the speaker position, a question comes to my mind. It's just a friendly suggestion that I maybe can improve your sound, nothing else. Have you tried to move the speaker more together and further towards you from the back wall? If not I would certainly try that. If you are lucky, it can give you better mid bas kick and better image in space and the first reflex will be easier to deal with for your ears. But, every room has it's own personality, so the position you have on the pictures may work well, but if you haven't tried... do so.
The best thing is thats it's for free!
