Personally I can't stand a plane with a lot of wrinkles or any for that manner, but I have seen raisins show up to the field from time to time and they fly just fine. The amount of wrinkles you have there on your plane is about about what I had on my two arfs and they came out just fine. I used a heat gun and some patience. I don't subcribe to the therory of sealing the covering to every square inch of the plane. Just as on the wing I only seal the covering to the four edges and seams on all the surfaces. Less worry about air bubble as it is distributed across the whole surface. And then one pin hole in the center and that takes care of them.
