It's hard to get critique on artwork sometimes, particularly flash. I posted on Newgrounds for help, and only got 4-5 comments that weren't really detailed.
Here is something I'm working on. I think I'll fix some of the sounds later and make them louder or quieter. Sorry for the large size, but I haven't yet optimized it, and it's very detailed.
It's mostly experimental, and I made it because I think people found my previous flashes too slow and lacking in action.
It's a WIP because I haven't colored in all of the frames or drawn in all of them yet.
