How could I improve my Patreon? (Patreon)

Hey guys cx 

I hope ya'll are well. I wanted to ask for your opinion. How do you think it is possible to improve my Patreon?
The growth stopped a while ago (over a year ago I think). The income stays basically the same every month. Things like this are really important to me because I am a freelance illustrator so I currently have no other income besides Patreon and commissions.
I really would like to improve stuff. 

I already was thinking about raising Tier 1 from 1 USD to 2 USD
The income decreases a lot when it is converted to Euro and this would make up for the money I lose. Before I would raise Tier 1 a bit I of course would ask you guys about what you think.
But maybe there are other ways to make my Patreon more attractive for people. 

Maybe there are things I can do to offer you more without working more. Since my final semester is coming up. So I still have time to rest. 'XD

Your Ideas and opinions are really appreciated and important to me >w< ♥
