You should at least credit the person who created the base image you worked off of [link] I'm not sure what's up with people on this site not giving credit where credit is do.
I have talked to him and I did not base my drawings on his drawing, I hadn't even seen his drawing before he wrote to me. The only thing I did was checking some images on google and I saw many pics of cute fillies that sat like that but in other directions so I thought "hey that's very nice I could use that." But anyways everything is sorted out
