I think you could have a problem with a strict MOT tester if those are structural areas, the impression is they are a lot of tacks and not a true weld, I doubt you have any penetration to the original metal...I have known testers poke a screwdriver under and lift plates which look doubtful
Sorry to be negative but it is of no benefit to you to say well done it looks great, I think you need more power on and the gas sorted, then you should be 'motoring' so to speak.
The wheel arch looks a good solid job though..so well done on that.
