put the funnels a bit further from each other, (move one of them a bit to the bow, preferably) and move the guns a bit to the bow, as the aft one now interferes with the rudder. the TT's : keep the forward one where it is now, and move the other between the funnels.
and for the freeboard: aft it is ok, move the midships deck up to the same level to be perfect
also, I joins gollevainens words, and I think this will become more of an CL/flotilla leader in size and weapons layout.
