I would have restarted with extruded foam had time not been an issue. I think cutting and refinishing pink/blue foam would have taken a bit longer, put perhaps would have yielded a better result. I’m not much of a model maker/fabricator so it could have actually turned out worse.
I also noticed you were from Canada and had to check out your site – it looks like you have a pretty sweet gig going. I’m out at Emily Carr. Did you go to school in Canada?
