Wow sweetie, this is a wonderful first attempt to drawing Usagi Tsukino/Sailor Moon with an expression coming from the anime/manga series! I especially love how you have drawn her in a chibi like style, as well as how beautifully you've colored and shaded her in! Excellent work honey, I love this very much, and you did such a great job!
Lol. Too funny! Depending on the situation I can totally see her doing this even as a Queen. She can't completely change! It's just not practical as a human being. (Aside from the fact she is in an anime character, but that's not the point!)
