Not sure if you're making signatures casually or if you really do want to get a lot better at sig making. I'm going to assume the latter and give you some legit advice .-.
Don't take this the wrong way, but it seems you don't really have a "guide" as to how to go about making signatures. There are certain fundamentals all good sig makers abide by, and when all criteria are fulfilled it is at that point that the sig maker can say 'this is a good sig' or something o_x i dunno. I would suggest reading tutorials to understand the basic fundamentals to sig making if you want to get better.

They're all long reads, but necessary if you truly want to get better at sig making.
