I Drew my favorite champion Nunu and Willump!! Opinions? ;o

Hey guys! my name is Ryder and im a profesional Platinum hardstuck Nunu one trick and artist, ive always wanted to become an artist since i was a young chap, I have been slowly making more and more drawings trying to improve and master my own unique, yet good looking style that can catch someones eye. Earlier this evening I decided to embark in one of the most challenging and important picture i have ever created in my life. This is my main champion and I knew I had to make the fellow Nunu mains proud! Personally I couldn't be more proud of the outcome, but we all have different interests/opinions and im curious to what you think! What do you think i could improve on, or is it just a perfect work of art? Let me know!
