Looks nice!
On the next one plan on a shrink fit of the rim to the center, that's how I've always seen factory rims done. The rim will grow a lot if you warm it with a good torch, one or two of those propane weed burner things would be helpful. Be prepared with a jig to set backspacing as it cools. Then mount it and adjust and check with an indicator before tack welding.
For this one seems like you can tack weld it and adjust run-out as you go, then finish the weld after you've got it true and secure.
