Please refrain from heavily referencing/copying other's art styles or designs, it's not gratifying to make other's style yours. And while having inspiration/references is totally okay there is a huge difference between inspiration and imitation, please work hard to develop your own style/designs rather than taking someone's else because that one person also struggled and worked hard to develop their own and unique style.
EDIT:
This not only goes to the deviant in question but also others who I have seen around which style is awfully familiar to some of my friends, acquaintances and other artists such as giannysuki, wolphee and many others.
