[I made the thread here cause there isn't an all purpose suggestions forum]
1) Your tiers scale (almost) linear. But the amount of money people are will donate doesn't scale linear. Someone who already donates 50€ is far more willing to spend an additional 10€ than someone only having 5€ available for donations. So I would like to suggest, change tiers to something like 5, 10, 25 and 50 €.
2) Give an incentive to make lower tier donation, and more incentive to make higher donations. I for example would have the bugget to donate maybe 5 to 10 €, assumung I'd be 18 already. But currently there is no reward for it, other than colored names. I'd suggest maybe a one time recolor for free once you first join. For higher tier patreons, how about early access to changes and news, even if they aren't final yet?
3), and this is only a small suggestion: On patreon you currently have to click "show more" to see the perks for higher tiers. I'd suggest putting the improved perks first, and follow it with a "And all perks for lower tiers"
This are only a small suggestion though, and they won't affect me for some time still.
