I like how realistic this looks. Normally I don't like art that has been taken from a picture directly. It's nice to look at but it makes me feel extremely stuffy. I think this artist has found a way to make things hers despite them not being her own creations.
An example of her work:
>Artist's name unknown, their DA username is ~bluesonatina (http://bluesonatina.deviantart.com/)
This artist managed to grasp a great point of view (perspective) in this piece. They also have great values.
An example of their work:
Techniques
>Cross-hatching
>Stippling (which I'm not fond of, don't like how it looks nor the amount of time it takes :P)
>Continuous tone (LOL)
