That's a good looking bow. To reduce set in you next bow, take a look at where this bow took most of its set. It looks to me like it's bendy a little too much at the handle to about 8 to 10" out each limb. The rest of the limbs are hardly bending at all. And from your unstrung picture, it looks like that's were you set occurred. Get the mid 3rd bending more and the handle bending a little less on your next bow and I'll bet you'll have 1" or less set. Oh, and heat temper.
You still got a good bow there.
