Hey buddy, that soldier is looking better than before but needs some work. Hope on to the Show us ya joints thread and do some practice and get feedback and repeat. Practice is obviously helping and i can see that you are improving - but you need a little more technical skills improvement here to get something reliable.
Butt splice crimps used as a knuckle splice are also a viable vibration resistant connection method and are cheap at the automotive parts store. I know it’s heresy here to suggest crimps here but the truth is crimps are easier to master and very reliable and so dead simple to test - just try to pull it apart. Also no work or solder hardening of the wire and often pre insulated.
For testing though those joints look fine - for riding they need fixing 
. That connector looks beat but should be fine to test - for riding you need to get some 5min epoxy and fix the wires into the jst connector so they cant flex and then use hot glue or silicone to lock them into place… i think we have already gone over that but it’s nice to put it in the thread for future peeps to see and learn.
Jump back in my dms if you want to go slow and plod through the trouble shooting with me but i think it’s getting to the point of frustration instead of fun here and maybe time to go do some chores or mow lawns so you can trade money for solutions. Lmk and hmu if you’re still struggling buddy, this is getting to more than the beginner thread can solve maybe
