I kinda prefer this angle because the OG spritework is what everyone knows. This design keeps it pretty consistent with the way the average person remembers Excitebiker to look. More detailed takes on the character could be fun like we got with Pit, but I think Excitebiker is the kind of series that rests more heavily on its simple retro appeal over any compulsion to modernize it like the philosophy behind Pit was.
We can probably look at Ice Climbers and Duck Hunt for a good idea of what to expect too. The old school characters tend to be simple with big round features.
