Gosh, you're really good at using the modern sonic style I must say! I guess this character here is based of some kind of canine? I'm a big fan of the colour purple and you've done a good job placing it into his design and also used a tone of it that won't make him look eye-blinding. You have also made it mix well with the lighter colours and that darker shade of grey goes well with it too! I really like his "mane" and how it travels over his back and down to his tail too! I really hope to see a reference sheet of this character in the future!
