figure idea (Patreon)

so I've recently had an idea to work in something for rewards, 

however because of how inexperienced with Patreon I am

I would like a little bit of feed back on this idea. I've recently had the idea to start doing small figures based on the games that I've been helping put together, they would resemble something like this for example:

http://www.furaffinity.net/view/10072767/

http://www.furaffinity.net/view/10116044/

http://www.furaffinity.net/view/10814438/

however, they would be colorless, more like a D&D game piece

at it's raw state. Also I would be limited to how many I could 

give away considering the limited supply of Resin within

a given time. 

If anyone could give some info on dealing with limited rewards please let me know and perhaps I can make this patreon page a bit more interesting for you all of you who have been such a loving support throughout these projects. 

thank you to anyone that can help.
