Once done, thrice concieted?

Remember that style from way back when,
Well I've taken another look and revised some here and there
Robotnik's got new shoes and colors + better shading hopefully
Our Luigi with added shading in some parts and a fifth green shade
Updated Samus, zss few changes 5th shade of blue
Revised link
Completely redone Zero Ciel and Alouette, I still can't beat trying to redo ciels head, no luck there
and a revised Miijii and Kos-Mos
