Wow, very very similar to my first PCB, a breakout board for the TSL4531. I ordered it from OshPark back in 2016. Used the exact same soldering iron, and a Quick hot air station, though it's the less fancy one than you have.
From there on I've made various PCBs, and thankfully they've pretty much all worked on the first try. I do take a lot of extra time to verify the design and double check all the datasheets.

(sorry for imgur, not sure what people use for image hosts these days)
I then went on to also make a BME280 breakout:
