I see you also reinforced the vertical seam where the cross member meets the longitudinals. I've had to weld up that area (and on the other front side also) a couple of times on my SC track car, due to cracks, and that's on a torsion bar car. Wish I could weld as well as you, though.

Do the raised edge punched holes contribute significant strength, like maybe reducing the slenderness ratio or something?
