Damn, that animation is great, I love it! The sprites look great, and the directional shifting shading is very well realized. Good job there Balthazar!

One suggestion though about coloring (and I think this is more like a note for Cybaster) - On the fully yellow frames there's hinting of tones (the clothed area is shaded with darker yellows, Boots/Gloves are almost white, Skin is a lighter tone than clothes) which should be avoided, because in the palette you probably won't color-separate the areas in those Yellow Frames, resulting in weird palettes with wrong contrast. FOR EXAMPLE. If someone does a palette with DARK GLOVES, WHITE CLOTHES and DARK SKIN, the contrast will look wrong when Vegeta turns yellow.

This problem is very common in the KOF characters with fire auras, like Kyo/Chris/Saisyu in their DMs, or a more recent example that comes to mind is Psylocke by DivineWolf. A solution for it that Vans thought up for his Kyo a few years back was keeping the DM frames with the regular coloring, and make the shining aura yellow via Mugen PalFX coding (As seen in this short clip, starting at 4:38, first and last Kyo combo). That way, no matter the palette colors, the Yellow Frames will always look good in contrast

Keep it up Team Z2!

well I need a few custom made effects for the character I'm working on. You think you'd have time to pitch in?
