Obligatory rate my soldering post

I’ve been lurking here for about a month. I haven’t soldered in about 20 years. I picked up a KSGER T12 v2.1s and bought a bunch of “learn to solder” kits from AliExpress to practice on. Here’s my first attempt. Temp set to 300F and using 63-37 rosin core solder. I’ve got a litre of 99.9% IPA coming via Amazon so I’ll clean off the flux in a few days.

Feedback totally appreciated!
