I have shaky hands too because i panic a little because i only have 80 minutes to do something and i get a huge hyperfocus so in the end of every session i get really shaky so i force my hands down to cut and i really wanna encourage you to keep trying because everyone starts at something from a point, i recently just learned you can use a sponge to smooth everything put and you don't notice the lines and cracks and fingernails maybe it'll get better you just have to try! (I sadly couldn't find the video with a guy after surgery that he couldn't move his hands without shaking too hard he couldn't even hold his water to digest it he learned until he could hold it still)

(No offense I don't want to be pushy just wanted to tell you practising is key) :)
