Buddhas at Wat Phu

The four Buddhas in the temple at Wat Phu, through clouds of incense smoke. Somewhere I saw these described, rather unkindly, as more like aliens than the usual Buddhas: I guess I'd have to agree, though they attract the faithful regardless. In the Pips are other Buddhas, one located further down the path to the temple, the other outside in the top Sanctuary area. I may be wrong, but to me both the "outside" Buddhas looked to be much older in style than the others inside.
