Soul Eater maka x soul Digital Art

Hello! First of all, nice fanart! <3 I really love the ideas and the colours! Well done!
Now, that might be a bit strange, but I have a question. A friend on mine is a big soul eater fan and stumbled over your fanart. She fell in love an wanted to ask you if she might be allowed to use it as a motive for a phone case? (She would ask herself but she doesn't have a deviantart account). Of course she would give credit to you whenever someone notice her case.
Thank you in advanced and I hope you have a nice day
