Alpha versus Epsilon. I wanted them to look different, so I skewed Epsilon in the way Caboose remembers/imagines him.
Some of the details I included:
Caboose does not remember Church's eye color, but he does remember how piercing and intense they felt
The colours are skewed towards blue, both because of their blue suits/environment (more reflected blue light) and because Caboose of course remembers blues and blue and reds as red, as is natural given the amount of time they spend in those suits.
Epsilon has more heavyset eyebrows because Alpha always looked pissed. In reality, when his face is relaxed his expression isn't that intense.
Epsilon is more vibrant and saturated because of the way Caboose reminisced about Blood Gulch. At the time, it seemed so much happier and lively than the life he was living in blue base with the A.I storage unit.
Epsilons hair is curlier, because Cabooses hair is curly, so his perception of default hair texture probably skews that way.
