Nice color scheme, but I think the pieces could have used a little more work. When I was designing my chess set I first tried building it to the scale you did, but in the end I went for a much larger board, as it allowed me to make larger and better detailed pieces.
I've never seen a blue and red checkered chess set! Kudos for originality all the way through it. And I think you did really well on making the knights looks like horses, but I like the blue & white one even better.
