I agree with the others. Well done.
Just in case you do something similar with the bars through the frame, if you don't want the welds to show, drill the frame and put the bars through with the bars being just inset from the frame, then you can plug weld the bars in the holes and grind the welds flush.
I have also used the hole technique to weld other shaped pieces to another piece so the attachment point wouldn't look welded.
Not saying I see an issue with how you did it on this piece.
