It's very hard to tell from photos, but my initial impression is that your car looks normal to me. The only concern I would have is that I can't make out if the front panel is showing a pale yellow gel coat or a roughened finish because the blasting has removed all the top layer. But apart from that, the rest looks pretty much standard to me. Perhaps the real reason is that your paint shop just doesn't want the job, painting Fibreglass is a much more involved process than simply welding on new steel panels and throwing paint on.
It's a few years since I did my Europa (2011) but I did the Elan in 2013 and took more pictures. Here's a couple showing the general finish I had, including a repaired front section that was badly fitted many years ago and after several attempts to stop it flexing over the years, I finally bit the bullet and sorted it out properly.
The first 2 shots are general, part way through preparation. The grey/white areas you see aren't gel coat, it is the remains of the polyester spray filler I used for the 90's respray. But you get the idea, the appearance is very scruffy at this stage. The key thing through is that it's smooth - ignore what it looks like and trust your fingertips to find faults in the surface.
The wing repair shows that it had just been stuck on some time in the 70s with filler and pop rivets, and not surprisingly 6 months after painting it would start to show cracking along that line. The later image shows the original gel coat which should be glass like but often isn't because it's very thin in places on my car. Don't worry too much but if glass fibres are poking through then they do need sealing otherwise they absorb moisture and will give problems later on.
A good starter book is Miles Wilkins "How to restore paintwork", #4 in the Osprey series. Out of print but often on Ebay for a couple of quid. He's also done one about fibreglass in the same series but for some reason that sells for silly money. You don't need it, there are other guides around equally good, but the paintwork one is worth buying. Dated information but lots of pictures and sound advice relevant to our cars.
