Close, but now the background is too saturated! Try to keep with that bright on dark look from the first screenshot or, if situation demands brighter colors, try for complementary palletes or more muted colors so characters don't get lost! Remember, visibility is KEY. Low visibility is one of the biggest causes of "oh, BULL shit!" enemy encounters, nix it wherever it's possible to do so without ruining the visuals!
And if that proves difficult, consider outlines. Makes things chunkier but way more clear on a variety of backgrounds!
