Glen,
I would say you are certainly making the most of the space you have and the quality of your work speaks for itself.
Are you planning to paint the underside of the boot? A bit of black satin paint will make it a lot less noticeable. I painted the underside of the spare tire well on my FIA and it made a pretty noticeable difference. Purely cosmetic but something to consider down the road. The real priority is getting the car on the road, but all in due time. Just keep doing what you are doing ...
