If Marvel and DC had a cross over movie, the mere concept would bring so much profit for both of them. It's not like they have anything to lose from it. I'd be really happy if one of those old Spider-Man and Batman comica became an animated movie. Even if it were direct to DVD, my childhood would just be complete.
I really like this. As a crossover, I actually like these Characters together. I remembered Batman Beyond. However, I had forgotten about the spider man from the future. I am impressed with the backgrounds and buildings. There is a lot going on here. Now is this your profession ? Or are you trying to break in to the profession to be comic an illustrator? If so, you are very gifted and I think this is the eye catching work that will get you noticed. Have a great weekend!
