Frank,
Interesting picture and very well executed. I like your choice of woods and see no gaps anywhere.
One minor comment: I think it would look better with a line in the background, beside the boar, where the boat sits in the water, to emphasize that the upper boat is sitting on the water and the lower boat is the reflection.
I am enjoying following your intarsia projects. I too am just dipping my toes into intarsia and planning to do more.
