Those look good.
I like your paint jobs, since they look nice and dirty, like they should, no doubt.
My issue with these, especially the canoas, is that the freeboard is so high.
On the tabletop though, looking down on them, I suspect you don't notice it as much.
I see why they do it though too, since they're designed to hold the standing figs, and to look right with them.
Really would have preferred separate sitting figures, and a much lower freeboard, which on real ones looks to be about 6" – 12" max. above the water.
From what I've seen on-line too, in my research, periaguas were usually longer and thinner, similar to the canoas, and people sat single file in them too. They might have one or more small sails rigged for travel across large stretches of the open ocean.
