Forgot to say that the mermaid is pretty. I love her skin.
This isn't a complaint, but it seems so odd to me that she is petting a jellyfish. I'm must admit that I don't know so much about 'em, outside the experiences at my summerhouse. We get some there. None of them are lethal, but the ones with strings hurt when you either come across stray strings separated by fishing hooks or when you accidentally make contact with them. I know she is only petting it, but since it has strings, my first reaction is to snatch her away from it, like I used to do with my cousins, and will do with my nephew and niece when they get old enough to play by the sea.
The watercolor texture (I assume that is what the background is) works lovely. I like her eyes, and how lively she seems.
The winged creature looks like art for a game. It seems relaxed, content, but still on guard, waiting for something to happen. Is it from a game or a series? in that case, what is it called?
