XD Sometimes you are just invaded by a stream of creativity and you just start drawing a lot without even knowing what you're doing or time to realize what are you doing.

The picture itself it's very interesting, though. As Liode mentioned the expression is kind of that of curiosity. I do not know why he/she is watching the plant, or what is remembering by watching it. It is hard to guess. We wolves are so enigmatic and contemplative. Maybe it's just watching it, and that's it. XD Overall, very good job, as always.
