kola2134 Well, luckily @Kroom made an example Valkyrie, and he allowed me to use it. I modified it a bit, and came up with some variants:
VF-1R Valkyrie

VF-1U Valkyrie

VF-1T Valkyrie

VF-1S Valkyrie

VF-1SI Valkyrie ("I" stands for "Improved")

VF-1H Valkyrie

VF-1V Valkyrie

Actually, I'm gonna make a separate post for this.
