If you think that's bad, then take a look at this:
What is this? Is this some weird blue ball thing that can open and close with those four square things? Is that really supposed to be a Metagross?
Wait what? The body is too small and gets cut off in a weird shape by one of its legs. Oh and there's a floating Beldum where one of its legs should be. wat
With that said, if Game Freak can get away with using a pile of blue rocks as Metagross's backsprite, then I think I can get away with my Tirtouga sprite, which I used the B/W sprite as a reference.
