Joints look good! I would maybe look into cleaning the contact pads on the bottom of the cartridge though. It may work fine now, but those things can corrode and it looks like yours may have already started. A liitle preventative maintenance could extend the life by quite a bit.
Side note on soldering - isn’t it crazy how easy people make it look in YouTube videos and what not? Like, they always just heat up and flow so perfectly and so quickly on the first try every time. I guess it comes with experience. It took me a long time to get the hang of it, and I still can’t do what those folks do. Anyway, your solder looks great. Proud of you, too.

More heat, more flux. That is all.
