this was just a rough idea that I never finished. If i was to do this again I would try a more smoky effect with the fox to make it work better.

I was trying to add colour to just where 'light' would hit to give the form of the fox. But I ended up pretty much outlining the whole fox. The background could have been emphasized more, maybe another layer to blend the fox in, but not too much as to make the fox disappear into the cloudiness of it.
