If possible, I'd love a picture to pixel-over (so, facing the correct way) of an Electric/Grass Pokemon.
How about a small-ish, round body, with a ring of leaves separating the two hemispheres. On the front hemisphere, facing down, to the left and out of the screen (the way Pokemon sprites face) is some sort of face. From the opposite hemisphere, which will be hidden no doubt, vines whipping forwards in the same direction as it's facing, like it's protecting itself with them. They are the predominant feature, and they have lightning spiralling around them. A kind of "coming towards you" effect on them would be great.
Tell me if I'm being a bit too specific here. I give you creative license to do your own thing if you think it looks good.
