that sonar is way to big, and 2 RAM's on a ship this size is way too much..... the 76 can do the CIWS on the bow very well, so you won't need that extra as well. also, there is no need for an sonar if you have no ASW weapons.... I suggest some torpedo tubes.
the RHIB isn't very well placed, but I don't know if this can be ehlped....
the draft is way too deep as well
