Welcome to the Shipbucket.
I'm afraid I have to disagree with Armoured man's comment - it's not a "pretty solid good job". Not above the main deck (though hull looks fairly ok, but I guess that adding of bilge keel wouldn't hurt).
Reason for that is simple - apparently the superstructure has 3 levels, none of them higher than 150cm including thickness of the decks themselves. In fact the hatch below the bridge is just 120cm tall.
On a minor note: in Russian classification, the "small missile ships" (Малые ракетные корабли) were vessels armed with anti-ship
missiles. And here there is just one small launcher of surface-to-air missiles for self-defence (and presence of such armament had no influence at all on the ship's classification in VMF). As a coast guard patrol vessel (as the hull colors suggest) it would be either PSKA or PSKR (border guard ship/cutter).
That said, I hope that You won't feel discouraged from trying to do more work in the future.
