My two pennyworth:
The music is not unpleasant, but it is unnecessary. Since sound is possible, ditch the music and add a simple voiceover. If possible, add descriptive text with arrows pointing to areas of interest, and have someone with a clear, slow speaking voice read a slightly amplified version of them. Or just say very simply what is going on.
Only a THP is shown. I don't think this shape of low-peaked sail should have only a THP, more of a combined THP/LHP going to the yard and one of the upper battens would be better.
No standing tack parrel (PJR fig 3.25) or standing lower luff parrel (PJR fig 3.26) is shown, and one or other would certainly be needed.
Although the topping lifts are shown as in PJR fig 3.47, I don't think this is a good way of rigging them; the lifting effect is concentrated too far forward. They should be the other way around, to lift the after end of the bundle more effectively. Running topping lifts (PJR fig 3.51) do not act in the same way as standing topping lifts (PJR fig 3.47) and this is one point in which I think PJR is not quite correct.
On the 3D, (2) is labelled as a luff hauling parrel, when in fact it's a throat hauling parrel, as above. Again, no standing tack parrel (PJR fig 3.25) or standing lower luff parrel (PJR fig 3.26) is shown, and one or other would certainly be needed.
Why is (3) clew mentioned in the annotations? This has no particular significance in JR. Other items could do with some annotations, such as battens, batten parrels etc.
