Super Mario 3, revamped and extended

[Cobalt Blue]

it surely is hard to recolor a sprite with a fixed palette.

I find it funny that you failed to notice the extra actions included in Bowser's sprites; especially the ones based of his animations from SMB on SMAS.

it surely was hard to move a few parts without actually putting much of your own to generate new content, or at least something not your average sprite edit afficionado can perform in a couple of minutes.

you did a good job on that arm, i can tell you. but besides that, you really did nothing that actually "improves" the original sheet. that walking animations you tried to make make no sense(i'm going to asume you haven't tested them). not even taking the shading into account since that point has been already discussed.

the way bowser is designed in this game is to resemble a t-Rex. there is no way he could open his arms all wide and so because he literally has no shoulders. at most he can swing them up and down and thats all(and that being generous). there is a reason why he got redesigned halfway thru SMB64 and in later installments of the franchise to allow him a wider range of movements.
