Let's see what you can do!
I'd really like to see where you can go with this. I'd say stick to your guns, give it a good, solid effort, and you'll see some good reviews. Good luck!
By the way - and you're probably already aware of this - but you can't hear your voice actors over the background music. You may want to adjust the respective track volumes... or... maybe not have voice acting at all!
I don't know if it's just me, but unless you've got some really riveting dialogue, is it necessary or even worth it to include it? If you want this to be a serious fight, then I'm sure you could make due without it. A simple, fast-paced, and elegant fight between the Blue Bomber and Flashman? I think that'd be sexy. Dialogue might make it cheesy.
I personally enjoyed the Megaman vs. Quickman flash (El Cid made it, I think) a lot. It didn't have any dialogue, and it rocked. God, I do tend to carry on. Anyways, voice acting - is it necessary? Something to consider.
