Your color palette works well overall, the pink/magenta against the dark blue creates nice contrast and mood. The issue isn't the colors themselves but how they interact: the bokeh circles and the motorcycle compete for attention because they share similar pink tones and saturation levels. On rendering: You're right that it feels a bit heavy in places. The hatching/texture is applied uniformly across many surfaces. Try being more selective. use that rendering style to emphasize form and shadow, not on every element. Also, while I understood that it must be water, I would push down the buildings to not have this small strip filled by water. Either that or make it bigger. I highlighted a blending white from the moon that looks like a leftover. I hope this helps !
