A good start. I see what your freiend means by contrast, thought. In my experience, it is always good to work with darker tones first, so don't put in too many highlights into the fur just as yet. Instead, work on toning down the shaded areas, and only then start lightening up the highlightened areas. THis keeps the highlights pure rather than creating mud, thus creating contrast.
I think you will also find that a real wolf doesn't have pink ears. They insides of the ears and the gums would appear very dark (unless the sun shines through the ears from behind).
It's not about how many breaths you take; it's about the moments that take your breath away.
