Her artist is likely to be Ask aka the artist for AL's Richelieu and AK's Surtr.
Wow she's gorgeous. I really like her outfit too. It's professional looking but also stylish. Also, I must admit I do love a battleship that's more on the slender side.
The white and gold trim makes it look from another faction.. I think a little red would help.
I don't think it'll help much. Red, white, gold is kind of a French thing if you look at the likes of Richelieu and Triomphant. Golden crosses are also generally a French thing in AL which Vanguard has far too much off. Honestly, Vanguard would probably look much more British if they ditched her white rigging and clothes and went with navy blue instead. Even with the British ships that have golds in their designs, their golds are much more muted than the very bright golds more typical with a fair number of French ships.
