Finally done! Because of all the fit issues, the tons of putty used and the constant going back and forth to patch up problems, I'm not entirely satisfied with the paint job, in particular Sakura's. But it will have to do. I'm shipping it to my customer in the morning: I took all the possible precautions and I used a lot of sponge to pack it, but I'm still afraid of the conditions it might be in when it arrives. Fingers crossed!
