Malak Nar - Dragon design for a personal project

I'm currently in development of my own fantasy world / IP and one of the pinnacle characters of the story is a huge dragon called Malak Nar (roughly translating to 'Fire Angel'). I'm currently still exploring his design and may revisit / refine it a bit further. This project shows it to the current stage I've deleoped the character / creature. I've taken inspiration from much of the animal kingdom, including elephants, scorpions, crocodiles, spinosaurs and pterosaurs. The next stage is to explore how he breathes fire!
