No real reads on any players, but was i right to fastplay this in most situations?

I would most often lead on the flop rather than check raise, but other than that it looks fine.

Usually, you should just lead the flop here, which makes the pot play very easily the rest of the way given stack sizes. As played, seems fine, you should simply shove the turn instead of leaving yourself .30.
