Overall? Very clean looking unit.
Not sure about the risers- some folk don't have the best of luck with them (not enough intake) But they look cooler than heck.
Hard to tell from the pic, but your grate seems to be sitting pretty high unless you are going to use a kettle lid. I use the flat lid too but my grate sits about 5.5" down from the lip. If you find you need more depth, it's easy enough to drop down and drill more holes. I'd do 3 studs instead of 4 or more- less wobbly if your measuring and drilling is "less than perfect" like mine is.
Good Job- Cook something already :-D
