Okay, I dont think you would enjoy my description, but here's what I thought when I was doing this:
Its rocky texture shows that this monster would spawn from rocky material (particularly meteorites). Hence, the word 'Meteor' is added to the model's name. For its design, it was based on insect (fly and mosquito?) combining with my own imagination, therefore the 'Meteor Fly' is created.
This monster is created from pieces of rock and it is controlled by an ethereal-like being (glow in the middle). For its tail/back wing, I have never thought of rocket while making it. I was thinking more to 'car exhaust system'. But in this case, it is 'energy/mana combustion'. So the monster's energy/mana would appear in fire form. You will notice that the fire only gets released whenever the back tail opens. And the fire gets released more quickly when in combat e.g: Attack Anim, Spell Anim.
There you have it. Bash me all you want, I am proud with my work. First fully made from scratch model. Custom mesh, custom anim.
