Well, here are some answers for your questions
YAAASSSSS!!1
One question I have with this is do they laugh when you get hit???
No, I mentioned before that they wont. Altough, if you ask someone who is making Mario Forever engines to give you the laugh sound then with Lua you may be able to
add the laugh animation
what happened with their eyes and their mouth lol
Their eyes and mouth look bad tbh because they lack of shading.
But everything looks nice and detailed.
I wanted to stick to the original, but I ended up with this
That's actually pretty close to how they appear in the game! However, I'd suggest working on removing the 1x1 pixels and possible adding some more shading.
That would be hard because the WHOLE GAME uses 1x1 pixels in his gfx and so does the Thwomp. There are a loads of GFX which use 1x1 pixels and trying to recreate them in 2x2 just because SMBX said so will result in something awful and way too different.
yeah the eyes and the mouth clash horribly. Turn the black's brightness up to 15 and it should be fine.
It should be fine if I had Paint.net to solve that quickly ^^
