These are absolutely gorgeous and completely out-do their vanilla equivalents. Your skill with modelling is amazing; despite their prerendered nature, these look right at home in SRB2's palette-based art style when side by side to a sprited object, unlike many other prerenders. These are just flat out superior and I would not mind whatsoever to see these sprites added in a future version of SRB2, whether it be 2.3 or a patch.
