I decided if I wanted to get the best criticism and help I should probably show more than just one work, so I plan on posting all the sigs I make from now on here and hopefully people can tell me what needs work!
I am very amateur and only know what I've taught myself/learned in 1-2 tutorials.
Heres a sig that I sort of looked at a tutorial but also sort of just randomly did stuff (earliest sig to date that I have saved)

Here's my first sig i actually took seriously (current sig)

Here's my second, this one took a lot longer than I've ever spent making a signature. Tried to follow a tutorial really closely. The text is temporary because i'm awful at placing text and typography kind of stuff.

Please let me know what you guys think i need to fix/change/improve on!
Also i hope i'm making progress on the last one because i spent so much time on it..
