Good for a first
I'm glad too see someone new submitting a first submission thats original. I really liked your black and white style. Some tips would be to take more time with your drawings. Make your characters look a little different, reflect their personality into the character. When a character is walking. Try not to just have them slide, have them in a walk cycle. If your still new to flash and having trouble, put something infront of their legs. I've been using flash for about 3 years, and I still have some trouble with walk cycles. You have alot of style with your animation, which is great. I recommend practicing just frame by frame work and tweens in random flashes, don't upload them to newgrounds or anything, and see what you learn. When you get good enough, come back to this X-Falcon idea. Nice for a first though, take this into consideration. Best of luck to you. Welcome to Newgrounds!
