Good job.
You might consider installing the turn the signals into the bumper something like this:
On my bumpers I run a brace from the outside corner of the bumper down to the bumper mount(3rd gen oem frame mount). This support will transfer any side impact on the bumper down to the frame, and also prevents it from being able to twist upward.
I have smashed the one on my '91 pretty good on the trail and the only damage has been to the steel diamond plate(dented/deformed around the brace).
If you ever try another shot at a plate bumper, you might tray making a wooden frame that you could then use to cut, and mount up the plate. Being a former carpenter that is what I did for my first plate bumper.
Since I was going to sheet it in aluminum diamond plate, I then used the wooden frame to make a lightweight steel frame.
