First time checking out the Art Portal but you sure do stick out of the crowd. I must say you are very talented at the theme you've chosen which appears to be a futuristic mechanised world with aliens in it. Like the others this is also a great piece and it remind me a bit of the Metroid Prime series. If you haven't already I trully suggest you show some of your artwork to universities or studios because this is great work. Please don't forget about Newgrounds when you make it big to continue and show us some of your pieces of art, I would love to see more.
