help spriting a pixel perfect force feild sprite

[Shadowblitz16]

can someone help me sprite a force field sprite?
its for a mod to a game called starbound which is a sandbox platformer.
I would like to have animation where it has a scan line rising up from the bottom refreshing the shield.
however I am bad at drawing 3d objects

I have tried attempting to sprite it starting from top and scanning to bottom but I can't even do half of this.
here is what I have done so far

Hmm, maybe you could take example on this or this.

see I need it to be between or equal to 48x48 and 64x64
and sadly looking at sprites doesn't help.
I have looked at so many force field sprites

maybe you guys could come up with an idea that would look cool and be easy to sprite?
or maybe instructions on a tool and how to make something like this?
