I had a non-punk design and a thick fat design, but neither one felt right and the Scorpion seemed warmly received. Compound Eyes doesn't seem to need much justification in real designs, though thick fat does worry me.
This guy has it all for a concert- powerful singing voice, Ngas smoke machines and mic arms for amplifying his yells.
Dragons usually have fierce appearances and grouchy demeanors, which this guy has both of.
This guy looks awesome! Only thing I'd say is maybe scale up the head a tiny bit (they seem to have Legendary proportions) and make the eyes/face more expressive and buglike. Definitely change the eyes colour; right now they blend a lot with the visor.
Decided to work on a third design
Based on both the Scorpionfly and Mantidfly, combining the most intimidating bits of each (tail and claws, that can also function as wings). The Ngas is like dragon breath I guess.
Edit: shrank head a little
The only thing I would say you could change would be to try and simplify some of the more realistic looking details, e.g. the small spikes on its head could be bigger, or the fur could be a bit more regular. Otherwise, you're golden!
