Your solder joints don’t actually look that bad. Ive seen much worse; and “works” is the gold standard anyway. You’re probably the only one that will see the board in person.
If you want advice, it looks like your iron was either too cold, or you didn’t work fast enough and your flux burned up before the joint set.
Mostly just visual in terms of shine vs matte. For the quality of the joint itself, lead-free has a higher melting point so you need more heat to keep it flowing nicely.
Your joints will do what they’re supposed so, so they’re fine. Chasing perfection is just a fun minigame.

It’s lead free solder. I think that affects how the joints look.
There are lots of LF alloys, some shiny some not. Your joints are fine, regardless of the alloy :)
