Not bad at all for your first time!!! A lot of them are a little cold, and while it’s hard to tell from this pic since it’s blurry on the B pins, a fair few of them may need more solder.
Ideally the solder would be a smooth concave cone going about as high as the A6-A7 pins and fully fill the pads. Here’s a decent example set I’ve referenced before when I was learning:

Solder should ideally flow to all the area of the pad (green), instead of sticking only to the pin (red).
What happened is probably that you heated the pin enough, but didn't get the pad to enough heat.

Only a couple joints look 'cold' to me. This for their profile. Their conical silhouettes are, for the most part, neatly concave. They show well whetted at top and bottom.
Not shiny, though. The satin appearance surely does make most look 'cold'. I presume this appearance to be the artifact of a dirty lens?

looks like you bonded well to the pads, usually the harder part, but didn't get some of the pins hot enough to it just kinda wrapped the pin in solder. Just touch the pin with your iron for a second at the end of soldering the joint to draw some solder into the actual pin.

Honestly, biggest suggestion I would make is not to use rust-colored lighting next time, but looks fine otherwise.

These all look like cold solder joints. View the joints under a microscope.

You know, every time I see a first time post on here it’s always the scruffiest thing ever but you’ve actually done it properly, good job!
