From the base look of it, I'd say your EULA is quite reasonable, and asks nothing that wouldn't be common sense anyway. It places no undue restrictions, and asks for no unreasonable conditions (credit on any work created with the product, for example. I won't say who currently uses such a condition, but I won't be buying any of her work). It's also written in plain English, which makes it that much easier to read and understand. Well done.
