ptoing: Thanks. That may end up being what I have to do.
CrazyMLC: Thanks. As for the awkward recoil...that's kinda the effect I'm going for. I'm not expecting something called a "BumbleBot" to be particularly badass. I *like* that it looks somewhat unstable.
Zoggles: Thanks. The rotors are counter-rotating right now - that's the only thing that makes sense, given torque issues. As for your (and others) concern that the flash might be to impressive...well, that just means I need to step it up on the big bad boys later on, right?

That is a challenge I think I will enjoy. As for the roof bits - I'll be making and showing some roof edges and transitions to break everything up.
Ultimaodin:Thanks. I kinda like the width of rotors as they are - that they look almost too small to actually keep it in the air, is awesome to me. Really adds in the "bumble" part of the bumblebot. As for the width of the blurred portion of the rotors, good call. I'll narrow that down pronto.
I like the Centipede idea. Maybe for a boss?
Okay, so all the transparency issues have driven me a bit nuts. I've started using another gif-making program to try and get around them. This particular program also supports APNG, so if you have a browser that supports it, you should see correct-alpha animated version of the GIFs.



How's that work for everyone?
