I looked at your additional pics, and all I can say is I sure don't see any noticeable blotchiness. I'd think any unevenness in the color is going to go away pretty quickly with exposure to UV. I think your "box" looks awesome.
In a way, you remind me of my Grandma. She'd bake the best pie in the world, then sit there while you're eating it and tell you all the things she thought was wrong with it...too sweet, not flaky enough, not sweet enough, too thick, too thin, etc. And it was still the best pie you'd ever eaten. You remind me of that. (And that's a compliment, BTW.)
