I'm assuming that there's supposed to be someone else inside that armor (I haven't seen the movie)? If not, then I don't think an empty Iron Man suit and Tony Stark would qualify as a dynamic duo, as the armor is just that, armor, not a unique individual.
That said, both of the figures look good and I like the beat-up couch, it reminds me of the improvised doll furniture how-to videos I often watch on YouTube.
