Sorry for the late reply..
Lightning is a thin jolt of fast moving energy, so I'd go for something that looks more like a crack in a window.. Much thinner and more.. fluent, I suppose.
:P good luck!
The rest of it is simply fantastic :)

Hey dude, I did have this posted in the MAC thread but I figured a VM would be a better idea just in case you missed it! Here it is:

I read that as lighting and was like "yeah, I suck at lighting"... but since it's lightning, would you mind elaborating on what your issue is with it? I've had a couple of complaints about it (so you're not alone!), but I'm not 100% sure on what the problem is exactly. Too many offshoots? Is it too thick? Or is it mostly an issue with how it moves compared with the other two lightning stems? I could see that as a problem since it looks like of... foldy... around the mid, but IDK. Thanks for the feedback, btw. :D
