On topic of the drawing: I like the idea and you have executed the theme quite well. The line that seperates the two worlds could have beens smouther though...

Answering Mobin70: Submitting artwork is pretty simple. You just go to the pink button on top of the page that says "Art". A dropdown menu will appear and one of the option is "Submit yours". Then you can just fill in the form they give you - one of which is the tags. Hope this helped!
