Beautiful vessel!
I actually thought you had shaped the bow wrong - then I noticed it was a black part of the camouflage scheme to fool the enemy.
I like that you have the pennant on the hull - very annoying that Silent Hunter III, IV, and V failed to include this basic detail on escort ships. Nice work.
One suggestion - tone down the bright yellow color of the life rafts. Paintings and color film I have seen seems to show these were usually a dark grey or brown, and did not stand out like modern lifesaving equipment. Of course, if you have a source telling you differently, then disregard.
