Constructive criticism on my vertical up please I stopped half way up to change my voltage. First attempt was 4.0 mpm wps and 18.8 volts and changed it to 4.0 and 17.8 volts
Not bad at all, just pause a bit longer at each side and travel across the face a bit quicker and the weld face will be flatter with a better transition at the weld toes
Like backpurge said, pause a little longer before weaving back to the other side, but the amp and wire spead don't say much without knowing the whe width of your base metal. But all in all, for a first virtical it looks pretty good.
