A scene from Ginga Densetsu Weed manga volume 16: Weed uses Battôga for the first time on a boar called Sancho. ...well, it's not really the mastered Battôga yet. It looked more like the anime version's somersault. But I guess it's really good try from someone who haven't ever seen the real Battôga. Also, Weed's ass is too long here.
I think the battouga Weed used in this volume looked more realistic than GNG's (and Weed anime's) version of it. It seems more reasonable that you could hit the target just once and not multiple times and the power it needed wouldn't require continuous spinning. Or maybe this is (just as you said) still in-progress-battouga and it's going to be more like the anime version. Nevertheless, I like this version better And your art of that is awesome!
