If you share the SketchUp file I and clearly describe what it needs to be “better” I expect a number of us will be able to help.

Your profile says you are using Sketchup Free (web). Since you are using SketchUp commercially you must use either use either SketchUp Go or SketchUp Pro, not SketchUp Free.
