Excellent work, looks really good. Forgot to mention that you did a great job filling the seam on R2's dome. I picked up some Tamiya putty (gray) to do the same on mine. Had never used any type of putty, but I've practiced on a couple of projects and really like the stuff.
What type of putty did you use? I know Bandai plastic can be finicky when it comes to oil washes, and I'd hate to use a putty that has the same impact.I put most of the dome together then aid the putty then a light coat primer then silver and hand panted the blue the top bits panted after and no masking was needed
