um
Well I suppose the concept is alright even though it's been done to death. Just one thing, if you're turning this into a series PLEASE DO NOT use drawings like those! I have a suggestion for guns, u can do tracing like most animators say, copy and paste a gun on one layer and then draw over it on a different one. Not being a flash artist, shimosan or guru myself i don't know how it works but I know I've seen better guns, also take some more time to do the drawings cause they look a lil sketchy from this trailer. Other than that it's good
Keep on keeping on
