can't go wrong with the HT version for the price, but this looks like something you'd see in that special wax museum in LA, just shrunk down to 1/3. I gave up the figures long ago. I have no issue with the likeness on this and I've seen my fair share of RDJ sculpts in my time.
Imo the head sculpt isn't all that great a representation of RDJ (Maybe Tony Stark, but not RDJ). Of course the type of material used, hair and paint app do push the quality up a notch or two.
I think I've been spoiled with that 1/4 Hot Toys sculpt. Nothing will seem up to par anymore.
