Hi all,
I thought I would share with you this tutorial I did for 3dtotal.
This is a low rez version of the book one (digital painting techniques volume 1) which you can purchase here ;)

Gathering Informations:
First of all, let’s try to find real animals that could live in this very specific environment condition. It’s always good to reference nature, and it’s the best source of inspiration to me.
The higher the altitude, the lower the pressure and atmosphere should become. Existing animals that live in high mountains, like Llamas or Deer Mice have adapted their physiology to survive in those extreme conditions.
This could be a good starting point to find design ideas for our creature.
Here is a website where I found some interesting informations:

Those animals have to get more oxygen in blood to transfer it to tissues. This means for our creature that it could have a REDISH SKIN
They also need less food. Our creature could be SKINNY
The depth of respiration increases. This means it could have a BIG RIB CAGE
“Pressure in pulmonary arteries is increased, "forcing" blood into portions of the lung which are normally not used during sea level breathing.
The body produces more red blood cells to carry oxygen,
The body produces more of a particular enzyme that facilitates the release of oxygen from hemoglobin to the body tissues.”
For humans, high altitude can cause some dangerous side effects which can also give us ideas for the design :
Headache, dizziness, fatigue, shortness of breath, loss of appetite, nausea, disturbed sleep, and a general feeling of malaise. HAPE results from fluid buildup in the lungs. Let’s add Holes on the rib cage.
HACE is the result of swelling of brain tissue from fluid leakage. The creature will also have holes on the HEAD TO EVACUATE FLUIDS.
We should consider adding BIG NOSTRILS on it to get more air in the lungs, and so more oxygen as well.
We could possibly add nostrils all over the body. He will also have2 necks, to double the volume of air coming from the nostrils on the head.
The name I chose is Pterocephalys . “Ptero” means flying and “cephalys” is referring to cephal, big head.
Most of the time where the atmosphere is low on a planet, the gravity is also low. Our creature could be adapted to this condition as well. He could be jumping very high in the sky and fly using membranes just like the flying squirrels. The Pterocephalys will need strong thigh muscles to be able to do that.
I am going to use Painter X, and a wacom tablet intuos 3 to draw this creature. Let's do a very quick sketch of this creature and see how it could move.
257
It gives us an indication on the proportions of the Pterocephalys. It could be between a bird and a squirrel for the legs.
