Just a handful of my friend  spacefag's Stellarmass aliens! From the top left clockwise, we have:

A Grey, with a silly shirt because Greys are jerks

A Ta'Koth, which I am not very good at drawing but hey

A dapper Daemon, in his older years when his metabolism slows down and he starts to put on some weight.

A ZurakiChaz, getting the feeling that at least one of the above three is plotting to kill him, most likely. :O
