This is so nice! I have tons to say about it. XD I love how the sketch colour matches the fur, for one thing. It's just noticeable enough to tell things apart and adds a great effect. The subtle shading and colour is very nice too! The simple background looks to me like one of those heartbeat graphs in hospitals, and it also adds a lot to the picture. Kind of a feeling of urgency, like there isn't much time left. The eyes looking slightly up are also great, to me it kind of seems like the wolf is looking ahead and hoping for the best. The water is a really awesome colour and I see it two different ways: I see the wolf hesitating to drink, and I see the wolf starting to drown. I don't know if you meant this to be a really deep piece, but it seems like that to me and I love it.
First off this is simply amazing! The intricate designs of pattern in the fur is very legit. The variety of colors you have shown really capture a viewer's eye. The facial detailed are faint but you can still notice the white lines that define it. Art always has a meaning but this has more symbolism than anything. You my friend have talent ^_^! The water has a cool wave to it and the shading presets in it will show the world that you know tinting and shading. Please by ALL means keep up your excellent and color assorted pieces of art !
