>>6480519I've never really noticed any particularly egregious mold lines/nub marks on my HMR valks. I think one thing to keep in mind is that HRMs are fairly small figures, only a bit taller than an RD when in battroid mode, so something that looks fine in-hand may end up exaggerated in a close-up review pic. Also, HMR's are packing a full three mode transformation into an RD-sized package, so concessions are going to have to be made, but I think they look great in all three modes.
In regards to plasticy-ness; that's something I've never really been bothered about with toys in general so I'm probably not the best person to comment on this, but in-hand the plastic used for HMR valks doesn't seem cheap to me at all, it feels like quality, sturdy plastic.
Regarding paint, all the important details are there. Verniers are painted, and major markings are all where they should be (UN SPACY on the legs/gunpod, Macross kites, jolly rogers, etc.) so there's no real glaring missing paint apps. It's actually not all that different from a standard Yamato/Arcadia release in terms of paint apps.
Here's the HMR VF-1S Hikaru compared to the Yamato release and an RD FA Gundam.
