Also don’t get discouraged by bad shots: espresso is like performing music; nobody, no matter how talented, picks up an oboe for the first time and starts playing Bach.
I mean, that doesn’t look terrible. Given what the puck looks like I would say you either need to coarsen up or fine up the grind. Helpful advice, I know. It looks wet, so my guess is you need to be a smidge coarser. Or you are tamping too hard. Or maybe the opposite!
It’s a good start, regardless, and the bruises will be well earned.
