In the left side portal, you have the silly EQ bars in the back drop that are obnoxious. They are wildly distracting, clash with the visuals of where the platforming is, and outright make it harder to see what's behind them. In your last game they were not as bad because of the color choice, but what you have done in this game makes this path unbearable to even look at, let alone want to play through it.
The green path on the right is fine though.
