Yes, as someone that got into photography many years ago:
Rule of Thirds—Honestly, this is the easiest thing to learn. It won't make your photos amazing or anything, but it is a consistent way to view any scene, which is very useful.
Then watch some random video on photographic composition. There are many different ways to view a scene.
Learn to shoot manual. Try taking good pics of fireworks on July 4th. It's tougher than it looks.
You don't need to get into editing raw photos, but it's fun af. I switched from Adobe Lightroom/Photoshop to ON1. I'd also recommend Affinity Photo. Unlike ON1, Affinity does not have a subscription and their software is comparable to Photoshop.
As for your photo, at a glance, I can't really tell it's shot as such as high ISO. But once you zoom in, you can see the fuzziness. Still though, I think it's kinda clear why you took the picture. It looks you're focusing on several interacting subjects (the bunny, the butterfly, the turquoise fence with the bunny outline) that all framed really well by the wooden house and the negative space at the top and right edges of the frame. I, for one, like it a lot!
Anyway, have fun! Photography is one of the hobbies I'm happiest to have. I hope it ends up being as fulfilling for you!
A friendly warning, please be careful when suggesting the rule of 3rds, especially to the less experienced. It's greatly misunderstood and as a result it generally causes confusion and boring photos.
