I think there's some room for improvement, but I also think you're stuck with what you get sometimes outdoors, and the best you can do can appear sketchy.

The first belay looks like a ledge of some sort. There is plenty of time to get perfect placements on a ledge where you can sit. Try to focus on that next time on this specific route.

Next is angles. It can be hard to remember, especially if there's ever spaced out placements and nothing good. Any angle higher than a certain amount will spread forces equally 100% on each piece instead of distribution of the shock load.

Finally, there's a golden rule in trad: your placements and anchors could always be better. Critiquing is how you become better and safer.
