I like it (you seem to have gone back to the single-nacelle variant!)
A blue cast doesn't have to be for the sake of TOS: the temporal anomaly seems to be putting out a bluish light. I agree with the Meshula says about the star pattern. There a very noticeable group of 5 stars. Also, the phaser pod is being cut off. Maybe you should move the ship up a bit, although then the ship would overlap that temporal anomaly. Try and he how it looks.
