Wouldn't have shared it if you couldn't use it! All yours and if you ever have any questions about working with a mug, feel free to ask me. I love to help.
Speaking of, TY, you asked me to transparent your picture. Along the way I noticed that it was really grainy like it'd been saved as a couple different file formats along the way, so I grabbed the original version and did my best to recolor it to the colors you had. Hope this help!
