G'day all, man it's been almost a year since my last post!
I've been taking a break from drawing with my attention occupied by both job searching (still no luck unfortunately) and with my hobby of model trains. That said, recently I decided to get back and try and finish the ship I had the WIP from before. I also redrew Sierans flag to fix some old niggles I had with it, mainly that it wasn't properly centred before, and the north star is now much clearer than the original.
As for the ship, here it is. Still don't have an appropriate idea for what to name it. My cruisers are based after rivers and the big battlecruiser things named after admirals at Tsushima. Maybe go with similar naming to the BCs or go for something else?

Excellent machinery, storage, compartmentation space
Excellent accommodation and workspace room
Ship has slow, easy roll, a good, steady gun platform
Excellent seaboat, comfortable, can fire her guns in the heaviest weather
Design has seen some evolution over the drawing process, namely the moving of the central turret forward and flipped to face rearwards after comments from Ace about the otherwise extremely restricted space for machinery in the hull. Any other feedback is greatly appreciated!
