I would not recommend getting help on this from NS, they lack sanity when it comes to ship design.
As for the update, I think the bow curve is the least of your worries, as it still has quite a case of multiple personality disorder.
Again:
~What is the intended purpose? If it is a frigate, you need to shift more towards ASW.
~What is the time period? You still have WWII Japanese radar and AA guns, a Phalanx, which is redundant and from a completely different era, a NATO ASW morter, and now you have thrown in a postwar US gun and a Soveit chopper from the 70's.
~The bridge is still too small, and you still have not changed the doors and windows. SB windows are 4x4 pixels, and doors are found on the general equipment sheet on the main site. (Although much of the part sheets on the main site are out dated. Use those found in "Parts Sheet Discussion" on the forum.)
