That looks good. If I understand, you made two images and combined them in an image editor? If you'd like to do something similar in LayOut so you can do the dimensioning like you're used to, here's a simple way to do that.
Use stacked viewports with the viewports on different layers and an intervening layer with a face that is not 100% opaque. I made an example here. Normally I would give the layers more useful names.
Layer 4 has the viewport for the scene called "Face assembly 2"
Layer 3 has a rectangle with fill on and the stroke turned off. I tinted it pink so it would show.
The Default layer has the viewport for the scene called "Face assembly 1"
Dimensions could be added in SketchUp in Face assembly 2 (put them on a layer that can be killed for other scenes where that assembly might show.) or you could insert the dimensions in LayOut. If you do the latter, put them on a layer above my Layer 4 so they can be kept separate from the viewports.
