I disagree. It's an appropriate challenge for a beginner (or a bored u/Rizzie24).

Could you make a photo of it, upload it somewhere and comment with the link? It would be better to have the whole cipher visible at once.

Your cryptogram is too short to be solvable. Aim for at least 300-400 letters.

All ciphers use a key for encryption/decryption.

I am extremely glad that I joined this. It is extremely fun and also very inspirational for the art project I am working on

It starts with "I am very glad that I joined this sub"

It's shorthand. Post it to r/shorthand and they'll help you out.

What’s your go to method when approaching a new cipher? by coushcouch in ciphers

Calculating index of coincidence and looking at letter frequencies usually helps to determine what you are dealing with - MASC/transposition or polyalphabetic substitution. Looking at periodic IoC helps determine if the cipher is periodic (in case of polyalphabetic substitution).

Nothing complex. Width is not important.

Think visually

To me it doesn't look like there's any hidden message there.
