A ha ha, thank you! :D
Enemies larger than in the demo of course will be. But I'm afraid there won't be any REALLY giant enemies, I'm still not a very experienced artist.
Very big enemies can come out ugly and take an unreasonably long time. But an enemy the size of a truck is always welcome! :D
Dude from what I've seen you're a pretty good artist. You have a great eye for colors and style. Keep at it and you'll get there. But trust me. You want to get there. And if you focus on just that, I'm fairly sure you'll get there in a reasonable amount of time. Also what if the scenery moved? E.g. if one of the bunkers in the first level suddenly shifts, like due to an earth quake. Or it suddenly rises and starts moving around on legs because it's actually a mech. That would be so cool. I guess I just like a lot of movement on the screen :D I think for very large geometry one thing people did back in the day was model out stuff in a 3D program, render that, then paint over it, covering it in full. It helps a lot so that whatever large geometry you're drawing doesn't start looking off. Think of it as a guide of sorts. Before they had 3D to do that, they would just draw out the mesh on paper or on a layer in the painting program. That's very helpful, too.
