Construction process continues...
Two more issues in the design:
1. Two small side armor pieces (parts 16L and P - marked on the photo) are to large and require trimming on top.
2. Fender (?) - inside piece is a bit to wide. Looks like designer forgot to reduce it by card thicknes.
I separated the inside part into three pieces to ease the process of assembly. All the seams are falling into inside corners so nothing is visible and it made my life much easier
I have to admit that I'm having a lot of fun building this model :D
