Your pinks and yellows are barely distinguishable from each other at 1x, so the whole thing looks like it's not shaded/highlighted at all. More contrast should help! If you decide to edit it, also try hue-shifting the shadows and highlights instead of making them simply darker versions of the base colour (e.g. make the shadows cooler and the highlights warmer, or vice versa). It helps with contrast and looks a lot less bland.
they looked a lot darker when i was doing it ill fix it
