Slick droids Daigo...
The R5, you should consider shaving off the middle eye though. I noticed in one ref photo that the center silver eye thing on that Rebel R5 is missing (dunno if you noticed or not). It'd be easy to actually just carefully slice it off with an X-Acto for a bit more accuracy (if you wanted).
The R3 looks great too... Good painting and you seemed to go the extra mile to make sure to cover up any tell-tale signs of the original droid. Always good to get those astro's in and I like seeing the R5 especially because you got the intricacy of his "deco" down right with the labels. Did you spray paint the actual paper? I was a little confused by your wording was all... Looks great regardless.
The Tibrians rock as well.
It seems a lot of people actually thought Ishi Tib from the POTF2 line was from Jabba's Palace when in actuality he's a Tibrian Militia Liason, as is his blue brother. Their uniforms are quite funky and added a lot to the "scene" IMO of giving the impression of the Rebellion being a single military force, but made up of OTHER militaries contributing as well... He, the Dresellian Militia that went on the Endor Raid, etc...
The painting seems simple, but effective on your Tibrians. It highlights what a fantastic sculpt that original figure was actually. If he were more articulated he'd be perfect. But your stand-ins for the Tibs at the briefing are fantastic as always DB. I like that you seemed to make the blue one darker for some variation between the two as well. Nice touch.
I'm hopeful that Hasbro redoes the Prune Face someday (with removable eyepatch so you can have either/or). That's a figure I keep hoping for something more poseable at some point, and less "specific" (with the eyepatch thing).
Great update man, thanks for sharing. I always enjoy your projects because they're big and strive for accuracy above all else.
