This is a nice one. Good job!
Tbh, GIMP is not my favourite. I've it in my computer but haven't opened it for years.
I don't know why. I think it's because I don't like the interface.
GIMP is no one's favourite. It's hideous, unusually complex, and unintuitive. The only thing it has going for it is that it's free and powerful: something that has kept me with GIMP as much as I dislike it. I'm changing over to Photoshop first chance I get.
