Are you using the inbuilt wire feed or do you have a spool gun?
I am surprised at the dirty surrounds and splatter, are you using pure Argon or is Aluminium wire available with flux in wire like steel is? Although I have welded aluminium over 6 decades with Oxy/Act and TIG over 2 decades I have only used MIG for steel. I have seen some videos of Aluminium MIG but those showed a cleaner finish.
You have done a great job with such a small amount of practice. I relate totally with your comments on wobbly runs, being fairly ancient myself I am starting to have the same problem particularly with TIG where I have to hold the gun with one hand at least with MIG I can use both hands.
