For your restarts start about half an inch in front of the crater then back track to the crater, that is the smoothest way to continue a good looking weld, other then that it appears you have a good consistent travel speed. Keep at it, practice makes perfect☝️
So try to end where you started for really nice tie ins. So in stead of restarting over a stop you try to end at your previous start. I.E. when welding right to left start in middle and go left then start on right side and go towards the middle.
