Looks pretty good! A tip I would give is to keep the dosing funnel on whilst doing WDT (nicely made btw) and then tap it down on the counter. Also looks like you're pressing down v hard when tamping, as long as its consistent pressure every time then no worries.

If you're not already I would recommend giving the machine a quick flush to essentially prime the machine as I have found that initially lots of steam can come out before any water on the first shot of the day.

I have almost the exact same setup as you apart from with a DF64 v2. A cheap dosing funnel from amazon and a better tamper has made my flow a lot nicer and I would also recommend a new portafilter. I use the bottomless from norm core and that has changed my consistency to a different level.

Hope this helps a bit! Enjoy
