I decided to go with a phoenix because I think they are very majestic looking (or at least that's how I imagine them), and I thought it would be easier to stay within the color requirements. I hope you like it.
edit: I have recently been informed that my entry strongly resembles another person's phoenix here on deviant art [link]
that I used as a reference. Though I did not intend to copy this person's work and did not know that it was copyrighted material at the time I must withdraw my t shirt from the contest. I appreciate all of you who have voted for my t shirt, but I would not be able to accept winning knowing that I did it unfairly. thank you to *Vyrilien to bringing this to my attention.
