Sure, keep it tight. First, lock the silhouette – a strong shape is worth thousands of verts. Use a few billboard planes for distant streets, no need to model every building. Reuse the same cube base, just tweak scale and a few faces for windows. Keep your palette to two or three colors, let the lighting do the heavy lifting. If a detail feels like extra weight, toss it – the viewer’s eye moves to the big lines anyway. And always test at a small viewport; if it still pops, you’re good.
