Hi there. Im very happy you like my work that much. The fact that you have used it for months now is an compliment with no measure !
You may use it for a Iphone cover on one condition, that you besure and remmeber to take a some fotos of it from different angles and post them here, og mail them to me - Since i would LOVE to see my art be used in such way.
