If we're talking about the rear (fixed) canopy section, I think it's more than acceptable. Remember that this, although 'fixed', was jettisonable, along with the opening section, and did show a joint, as it was not 'blended in' to the fuselage.
Once the main canopy is in place, and under 'normal' viewing conditions, as opposed to a macro lens, I think it will be fine - OK, perhaps not as good as you'd like it, but good enough.
