Congratulations on your first patrons! This is an amazing and great step and it is so great to see that people love what you do! =) The things you offer als rewards look pretty awesome, too 
I wish you the best of luck for reaching your first goal! =)
It is actually cool to see what others offer, I enjoy browsing through other people's patreon pages! =)
I draw the webmanga Remember and there are several things you receive on the lowest tier:
- Early Access to the newest comic pages
- Patron only WIPs and sketches
- occasional bonus comics for the main story (in that style)
And on the $5 tier, the rebel tier, you get quarterly sketches drawn and sent with whatever you want me to sketch =) These sketches can be collected and "traded in" for a full colo illustration, depending on which tier you are 
I started out with a monthly sketch tier, but I had to limit that to few patrons, because otherwise there wouldn't be much time left for my comic ^^"
On higher tiers I let people influence which bonus comics I draw, etc, plus if there's something NSFW-ish, it's going to these tiers, too =)
Mind you, I am still at the try-and-error stage myself, but maybe we can learn from each other? =)
