You can do better
Here are some suggestions:
1. Don't make it too similar to other movies (this Flash is similar to the Sonic the Hedgehog movie Randy Solem made, but this one has no blood)
2. Don't mix sprites or bittages (like taking Sonic Advance sprites and putting them in Sonic 1... trust me, you'll get a better score if you don't mix them)
3. Make it longer. Really short Flashes were considered good on Newgrounds a few years ago...
Hope those suggestions help. ;)
