Fabulous Hyena

The main aspect that captures the eyes is the expression of the character, his eyes and mouth are very well done and they give the idea of "badass". The expressions impact is also helped by the sonic-like facial anatomy. The posing is great and I like the hands and the fingers. Shading is simple but essential and it gives more depth to the character and adds extra detail to the overall piece. If u want to push yourself further u can try making the lineart smoother as it seems a bit rough, it would be a nice try and it would improve the pic even more.
