You can just say you used the picture as a reference or traced it, just don't lie about it.
Okay, I did trace some parts of it, and I won't lie next time if do so. I just had this same problem with Pebble and the Penguin pics at DeviantArt, only there none were traces.
But there wasn't to much on this one that traced, only two or three things that I had trouble with, and Mumbling mentioned two of them, the third was the head (which is the one thing with LBT characters I normally have trouble with).
But other than what Mumbling and I mentioned, nothing is. But I won't post any more of Ptyra's characters again.
I just wanted to do something different than my characters or movie characters.
