nice image, not 100% perfect, but its good for a 1st try
Also its got similar style to the original drawings ( from tv series) and improve by your imagination ^^ its very good, i dont see how critisizings going to help anyone, in fact how well can you v draw cause i havent see any of your work yet? so anyway a good job to the artist in training ^^ keep it up and we're all here ( except the guy metioned earlier) to help you
