The main thing that attracts me to this image, is the lighting and depth.. I I love how the light shines how it hits the wolf but isnt evident in the background. It really does help enhance the 'indepth look'

The eyes of the wolf are rather friendly too.. Since it is a speed paint, I cannot be critical on the definition and fine detail of the hair. though I think you've accomplished that effect nicely here.

There is one thing that seems to bother me, I am no pro with drawing wolves however the maw of the wolf does seem to be a bit far to the left.. perhaps its just me, but thats all that really stands out to me.

other than that i do look forward to your bright eyed and highly personable images<3
