Yeah you can work a little on that.
You can remove the main sail (as brigs of this era usually didn't have one), make the four course a bit longer towards the deck, and make the other sails shorter so that when looking to the fron, you can see the crow's nests between them.
And the upper yard of the spanker sail usually goes to the main yard of the main mast (not to the main topyard).
For the names of the sails, click here.
But outside of that, the sails look good, and I like the use of sails between the two masts.
I see that you've also worked on the headrails, it looks perfect now
It's becoming a very nice ship and when finished, I think we'll have another frontpage article
