I like the rendering but the nose seems to be almost merging with the lip, I'm not an expert on wolf anatomy but I know that it doesn't seem quite right. The 'cartoony' element contrasts very strangely with the realistic fur rendering.
Thanks for critiquing, I fixed the nose. As for the cartoony element, I guess I can't help that here. Perhaps it's the hair or how the eyes reflect light? You or I are used to seeing animals with hair in movies...cartoons, so that might reflect on the cartoony elements.
I need to learn how to do fur... and the nose texture you and others do, it never clicks for me! xD
Background is awesome too. <3
