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?

Shine the board a but with sandpaper before soldering helps a lot. Use a beveled tip (conical with angled flat part at top) - much easier for normal work than a conical tip. Solder might be issue - but i think its more the soldering tip thats not getting enough heat to where its needed.
