From what I've seen of the Kelvin, I really like the look of her and it looks like she takes on hell of a beating.
UPDATE...
The first two pics are of the textures for the b and c deck.
The second pic shows some of the saucer rim detail including the shuttle bay on on side and the cargo bay on the other.
The next pic shows a side view of the Kelvin because someone asked for it.
The last pic could be my version of Enterprise. Or not.
