Alright, I've wanted to finally have a little sort of ref for my Xenosapien self, so here's one done by sovietfuturistic. I'll probably have a full one made by him, so this is what we have for now.

So basically, for my xenosapien self:

Height: 5'9" (176 cm)
Weight: 128 lb (64 kg)

His body is like average, but not too slim.
His skin colour is grey, while the eye colour is brown.
His horn shape is like the design shown in 5m ( https://cdn.discordapp.com/attachments/711327964347891803/712016927874351226/Not_main_characters.jpg )
His eye pupils are both sharp (like a cat's eyes) and more rounded. It also functions like cat eyes too.

For clothes, it's black, with skinny sport pants and a hoodie, and white Vans shoes designed as a "white/black checkered" pattern. (though, it isn't shown here) The inside of the shoes have a white insole. The colour of the soles on the bottom of the shoes are brown. The hoodie is designed in a black/white checkered pattern like the shoes. His shoe size is 11 US/44 EU, which is also printed on the insole of his shoes, so every micro knew what size of the foot will enter the shoes.
He also has white briefs and undies, much like normal ones.

Xenosapiens may look at most like humans, but some differences include: no nails (which means their feet and hands are smooth), mostly male, are gay and have child birth capacities (because they don't have females), and the head (because they got the horns too).
Their sweat can also smell differently. Justin's sweat smell could be like car fuel, but he can activate the sweat smell whenever he wants to, so in most cases, his sweat doesn't smell, unless he wants it to.
