Awh, not only is that mermaid beautifully drawn but i have to agree that its the positioning that makes it even better then it would have been just being on the front like the majority (me included) have put our designs. Kudos!
I really like this shirt! you got my vote ^^ Clean design and cool idea. The one thing i would sugest is some colors, because the mermaid is kind of desappearing in the shirt for being purple too. But still a good job! Please check out my medusa shirt [link] or the others i made if you liked it! [link]
