My advice to you is to practice whenever you can. Try to replicate items in the real world, or maybe build something random. It’ll take lots of practice to get better, and I think my builds can use a lot of work too. But all you have to do is spend maybe an hour or so just building things.
These kind of topics have been brought up and made before in the future consider searching you will find something helpful around the forum.
Booming a better build or wanting to improve your skills it all comes down to practice and patients. Since you found a style you want to produce in historical builds always find objects based off of a reference image keep experimenting with different styles And technique. Don’t be afraid nor scared to try new things if yo cant find things around online use images and try to recreate it to your own abilities.
I’m not going to go into details since there are numerous of threads here is a thread with useful information and something you could take along the process.
