So... you just donated to someone that you likely haven't even met in person, but still want to support for all of the cool art that he makes.
Since I know the guy pretty well, I'm pretty sure he's rolling around on the ground in happiness right now, and you are helping that guy achieve dreams that he never knew to be possible.
In all seriousness, never feel pressured to donate more than what you feel capable of giving, and know that you are the kind of person that I love to make smile with whatever I can create.
With sincere thanks,
William
