i like betting a bit more on the turn, like .44 or so. Im iffy about the river. Checking is always 0 ev, but i think betting might have some value. I think some weaker aces and some weird queens might still call a river bet of like .7 (though this leaves an awkward amount left in his stack), but then again, there are likely some draws in here that just improved. Really though, i dont think checking the river is a huge mistake, at worst its a small one.

edit: of course reads and a question might be necessary to give any further advice
