No matter the angles and perspective, those engines are much bigger in diameter relative to the saucer than those on the TOS ship.
It looks like the scale of the ship is close to that of the original, though, based on interior deck heights.
Many details on the saucer resemble the TMP ship - including what look like phaser emplacements on the very forward edge of the saucer top.
Details here may turn out to vary from what the final ship will look like - remember how much adjustment was made to Kong's face (in the Peter Jackson film) after the initial images were released? Details such as, for instance, the placement of the registry - that may have been done simply because they wanted it readable from the angle they're rendering here.
All in all, I like this a lot.
