Not sure I agree with either of those suggestions, and they seem to push in opposite directions. The high level of detail on the insects keeps the focus on the insects, and the low level of detail on the background allows the insects to stand out. I can read the scene just fine the way it is.
I would remove that factory-like structure from the left side of the background. Unless the game is about dystopian industrial hellscapes (which can ironically be quite pretty), nobody wants to look at a factory. Replace it with a ruined castle or something, or just leave it out entirely. The two background features, the farm and the factory, create a fairly symmetrical composition right now, and symmetrical is boring. I also think that the transition between the green field in the foreground and the much darker and less saturated background higher up is a bit too abrupt. Maybe bring those colors closer together, or add an intermediate color in between.
