Smaug vs Saphira WIP

I wondered if smaug and Saphira got into a fight who would win? I think it will be Smaug but I'd like to know what you think

Smaug was drawn from memory and one single shot of the head from Google images so don't go off at me if I got him wrong.

Also Saphira is a bit too big compared to Smaug, she would actually easily fit in his mouth

I will be shading it and adding details it just will take a while so I thought I might as well submit what I have been doing.
