Firth Clone
You have a cool premise and some great ideas (loved how he flew around with his umbilical cord like a helicopter), but for me all that is overshadowed by the shameless "borrowing" of David Firths style. I know most art is just imitation but you could try to be a bit more subtle about it. As far as further episodes I think this has a lot of potential. Just try and carve out your own niche with it. It's great getting inspiration from other flash but you don't need to use them as a blueprint.
