You have such a nice gallary too! I have to say that your style is uniqe and magnifient! In my opinion you don't really need to change everything, just make it more realistic (like Hayao Miyazaki ^^ for examlpe). I wish you a good luck for the future and your art career!
P.S I'm really, really, really sorry for a such late reply! ;-; I had a lot of stuff to do last year and didn't saw it until now! Hope you understand!
