Retvizan in 1901 should be painted in pacific white w/ yellow funnels. And, please don't respond w/ "it's my AU". I like your drawings although some need improvements in accuracy (but that's something we all can benefit from, on the other hand!). If the ship is depicted as of during the Russo-Japanese war, then it's not accurate either, since the Pacific Fleet adopted a greenish tinted grey camouflage, but many vessels retained their yellow funnels, at least for a time.
It's - well-known fact.
1901 - the date of entry into service.
