It doesn't matter that you sell for money. I will be glad that the collection will be bigger, if you don't mind that you are not the author. I was inspired by you. You have full right used it however. Or I can delete it right away if you mean I'm ruining your business.
Thanks for clearing that up! In no way I think you're ruining anything (complete opposite is the case!), I just wouldn't want to take advantage of you and your work without making sure it's really okay for you. :)
