It's art. Art is never easy.
Anyway, texture is easy to fix.

Let the guy do his thing. You have to remember his dad is a pro. Always cracks me up when people in forums pretend they know better than people that make money from what they do - it IS a different level.
Just for the record: I never tried to pretend I know better!
It's just, that his dad is a pro with paint, but not with keyboards. He might not even consider the changing texture to be an issue.
I just wanted to remind vhaarr that it is (he obviously thought of that himself already) so they could take that into consideration. I'm not doubting his dad ability to solve this issue as well once he knows it is indeed an issue.
But it was my pleasure cracking you up.
Easy solution to the lettered key problem.
