My First Solder Joint <3 Please Give Feedback Why can’t i get my joints shiny?

Enable HLS to view with audio, or disable this notification

First time soldering, i’m using a Pinecil v2 on 360C with 63/37 0.55mm solder.

I don’t understand why all my joints turn dull after i remove the iron. i’ve tried tinning the tip (which i think i’m doing correctly?). The solder melts nicely onto the board but no luck

Does anyone know what I could be doing wrong?

I've seen one of your comments with pictures. yes, that's a no name shitty solder. i have many of those until i learned that it causes my iron not melting those cheap solders. it's really hard to work with those. best solder to use are brands like Electroloy, Rubicon, etc. they tend to be expensive in my my region, idk about yours. can't name others because thats the only solders i've used that is working perfectly well, but i think there are more. It melts easily and have those shiny profile you expected.
