Galaxies for Qinni

I used your picture as a cover picture for a tribute poem. I didn't think anyone would find it disrespect or bad to use their drawing for a poem provided I gave a link to their art; it's kind of like a free advertisement. But, it's come to my attention that some people view things differently, so I wanted to ask you if you find it rude so I can change it to something else. I'm very sorry if you find this disrespectful.
