Looks good for a silhouette or something. Did you make it from scratch? And what's with the white, why not just keep it all dark?
looks more like a desert fox than a jackal, and I think three tones would suit it better than black/white/transparent. I'd personally replace the transparent spots with white and swap the current white with a 60;40 grey (60% white 40% black). Should make it look like main light source is the left and reflected light coming from right.
