Well it looks good for the start of vectoring. Though some improvements are needed to make it look more good. First thing is that improve the shades in the vector. You know like some a bright color than a bit darker than the first than again a bit darker than previous one. Second thing i notice is pentool thing. You see when you do curves they sometime are not done smoothly. To do it hold alt and click on one of the two points and hold down left mouse and drag it. The ears also need improvement. But you will improve as you move forward and make more vectors. I have a good detail tutorial which will help you lot with shading, pentool and other things in vector.
