Arcusaurus

This was a Dinosaur who lived in the Early Jurassic era. It is unknown how exactly this dino looked like , but it is know that it always had a scar (because it's skin was vulnerable to attacks) :
As you see , that is a scar with blood coming out. The scar healed usually after a day or two , but the blood still keeps leaking. Another thing is the spikes on his head. something like these two , only the spikes go as a line (not a circle). Took me some time to make this. Diamonds are appreciated. Thanks.
