The sail is a bit small for realism sake...I LOVE IT!

Epic First attempt :)
Keep up the good work :D

I LOVE this. Pros - the Sails and the shape are SPOT on. It's a decently sized frigate vessel and you managed to scale everything to it proportionally. My only critique would be to maybe add just a touch of color to the hull, unless this is a stealth vessel, in which case, you nailed this 100%. +1 for you, sir.

some constructive criticism^^ :
the overall shape is good for a first time attempt at a flying ship. i have seen much worse. but the shape is good.
for the coloring meh, i think it is shaded a bit too dark if you know what i mean. extra colours and patterns would be cool. a pattern on the sail isn't a bad thing i think.
aside from that, could use some more interior i think. the kitchen, brig and dining hall are a bit bare.

for a first real attemt: good job, but needs improvement^^
