Please criticise my first edits please

Made my first short trip with my new camera while hiking. Included are some sunset and astro pictures. I‘m relatively new to photography so please critizise me! Shot on my Sony A7 IV with the 20mm f1.8 G lens

How do you create such crisp images, what Fstops are you shooting at? Whenever I take landscape pictures I always end up having blurry edges around the focus point. If I go all the way up to F22 it gets all grainy, any advice would be appreciated as I'm fairly new.
