Doing a side by side. MM doesn't have visible front teeth, his ears are smaller and fully black, the silhouette is different. But the shape of the face and features, including where the shape of the black fur decends (at the widows peak?), the eyebrows, the eyes with white, all look quite similar. To me it's much closer to a modern Mickey than the original flat black and white.
