Certainly interesting work of that duo of Robotropolis. The first element I notice is your concept of Snively, which is very well-composed here. I love your angular details and subtlety of design of his garments. For his stature, it adds markedly to his visual strength of character.
Robotnik's porportion is rather different, giving him a stance as if he were constantly bearing down on whatever is unlucky enough to be caught before him. He certainly has a tougher appearence, his ferocity underscored by the stronger linear/outward thrust of his shoulder armor. His bulkier build and sharp visual elements of his boots and surrounding uniform are nicely contrasted by his rounder belly and more prominent suit-cross.

Well done, Geno.
