dont be so judgemental about the amount of colors they use SR, the fact you come from CV which has an apparently similar but diferent technique doesnt mean that CD's is invalid, they have a reason to do what they do and there's not only one way to sprite.
first of all I dont think CV style is all that similar to this, honestly I dont think you got the style at all, what you did just looks like an oddly shaped and fuzzy CV sprite.
remember the DC sprites were meant to be displayed in CRT TVs, DC is superior to CV in portraying detail under blurring filters.
zoomed up all these shades might look a bit overachieving, but when you look at it in high res in original size, or in a blurry screen you can see how each pixel comes together to give a very good idea of the shape.
think of DC sprites as sprites that expand the theory of Selout from just an outlining theory into a shading theory, it's all the same principle and ideas but applied as a way to convery all of the detail in the sprite, I think DC sprites have a very deep intuitive understanding of AA theories.
That is also why I think this is mostly pointless, the ideas in DC are interesting because of how well they use AA ideas, but to really be able to take a deep look at this we'd need a drawing tool based on darkening/lightening color cycling, because practice is always behind intuitive understanding.
