Pretty good redesign of the vanilla FG.
Try experimenting with sprite edits along with the ones you already have and simpler "vanilla-esque" custom sprites like the Poison Mushroom for more of that New Game+ feel.
Don't forget mean level design, this is Lost Levels, right? Give 'em hell.

To be fair the screens don't show much at all from the stage so...
Also I don't know what you could add to the second screen outside of coins circling the platforms.
