Mario In Sonic 1

[StarSock64]

-Sonic's body is always 3/4.
-Enlarged limbs would make it impossible to animate, and would look unnatural/stubby. (As you can see with the last sprite.)
-It looks nothing like the SMRPG sprite.

-yeah, but yours is facing a little more towards the screen, so you should probably turn it towards the side a pixel.

-I don't know what you mean by "impossible to animate" but maneko probably meant that long limbs are pretty much part of Sonic. I know Mario clearly has a different anatomy but if you want to match the style you might want to just experiment a bit. I'd say the legs could probably use a little boost to them in particular.

-...yeah, I dunno about that one

It bothers me that his feet aren't sticking out from his legs, also
