I would prolly think your tilsets looked amazing :P
But I would also not personally be comfortable setting a price on something I didn't feel was worth it/up to my standards. So fair enough :P
I did have a price on something once, but I felt bad and gave the money back xD
Also, just noticed I bought your icons on a sale....That means I can buy another! As I was already willing to buy it for full price ''nods'' yes, that's how that works :P
