It's really amazing work and different from a lot of the other tribal wolves out there. There's a lot of emotion to this piece and to me, it seems to have a feeling of sadness/loneliness because of the downward motion to the lines. I feel like it would be a great tattoo to represent a loved one that someone has lost and misses.
The only thing I personally don't like is the small break in the line below the circle. But with that said, there isn't anything else that I don't like about it. And as with everything else I've seen from you it is absolutely amazing!
