Elf woman in photograph

What's wrong with this picture? It's a woman dressed up in a fantasy costume, I don't know if she's cosplaying any character, probably just a regular cliché'd female elf archer, which the fantasy worlds are always full of.

Mistakes:
There's really only one. The stance. Why is she crouching like that and thus holding her bow diagonally? That archery form is not really good. Her stance would be much more solid if she would stand on her two legs, back straight and all. She's also aiming very low, is her enemy coming out of water? A watergoblin (Vesihiisi, like we say in Finland)?
There seem to be a small trend that regue-like characters have to crouch when shooting with a bow, and actually, they must be in crouching position at all times, whatever they're doing. In games like the Elder Scrolls series, when player crouches, he/she gets more power out of his/her bow. That's so horribly wrong! The power of the draw actually weakens if you crouch and hold your bow horizontally, like they do in Elder Scrolls games.

Good:
Her archery form is otherwise good. I just see no point of being crouched, and even on so slippery surface. There would be a much better place for shooting a few steps back, not in the wet stones of the riverbank.
