Cybertron Transformers out of package

Had this Transformer Cybertron leader class 2-pack sealed in its original box for quite a while (think I probably got it on sale at Costco), and finally released them from their packaging as a house-warming ritual and surprise for my 3-year old nephew. Their design and electronic features allow for some fun playtime while their scale and articulation still make them pretty effective drawing reference models.
Their humanoid facial design is fairly close to the original Generation I style of the mid 1980s. My robot sketches often tend to display a fairly heavy influence from the Transformers robots from this time period.
