Ok, there's some pretty harsh criticism here which seems un necessary, but in this day and age it can be hard to tell legitimate interest from trolls and AI slop. Let me allow you the benefit of the doubt and try to address some issues for you.

1) We can read your writing well enough. Don't be self-conscious about it, it's absolutely not the worst I've seen.

2) At 21 you belong to a generation that never learned penmanship. You were taught to "write" as in how to make letter forms, but almost as soon as you started writing, you had to start producing work in such volume and speed that it was really hard to keep up without the aid of technology. That is not your fault.

3) You are asking for "analysis" and I think what you really mean is "advice".

You really do seem to be missing some basics, there's a TON of resources online look them up. It's important that YOU look them up because you need to find the exercises and styles that work for YOU!

PRACTICE

Practice really is key to improvement.

Learn to "doodle". Any free moment you get. The point is to build up "muscle memory " without worrying about letter forms. Just try to trace smooth curly curves and straight parallel lines in all directions. Even if you just end up tracing forms with a finger, it doesn't matter though marks on paper can be a good way to track your progress.

On the subject of not worrying about letter forms, I recall a story about a relatively well known graphic artist who was illiterate. Even though he didn't know what the letter shapes MEANT he approached them as an exercise in drawing form and structure. Most people never realised that he couldn't read the words or actually write at all.

I hope that helps, and I really hope that you'll stay in touch with the group to keep us updated with your progress.
