This is some concept art for an alien race I am designing for my conworld, they are called the Sullíhlod and are Silicon based life forms who live on a planet I have decided to name Lushlod.

Some more information on them is below:

The Sullíhlod have three legs, 1 of which is an adapted tail.
They have 2 arms that are shorter than their legs and close to their mouth.
A 'single' eye containing 2 pupils with a slit down the centre.

They range in colour from white to blue, but are normally grey since their planet is very hot, plants on their planet have white trunks and dark red leaves for photosynthesis. Animals on their planet are similar in colour to the Sullíhlod, some are even darker and red.

They breathe in Nitrous Oxide and make use of Ammonia to store energy.

I will add some more concept art when I draw it.
