You look at young human, 25 summers, maybe a bit more. First thing you catch about him are messy hair on his head, you may have trouble defining color as it shifts as a light changes, from bright light strands to much darker shade, at a times they can be seen as bright red.

Most of the time there is a smirk on his face, accompanied by few days worth of growth  - but even that does not make him look any older, his somehow bright face makes him look more like a teenage boy then a man - along with his slim body, fare from that of a warrior.
Only thing that is left and out of ordinary are his eyes, bright green, with a spark, that leave person watching him unsure if they are just a bit odd or is there an actual difference between him and other humans.
