This is an earlier drawing I did from a Mark Crilley How-To video. All credit to him. Only thing I did differently was to add some red to the scales. Video Link: https://www.youtube.com/watch?v=XId8ethxg2M&t=0s&list=PLCD2CF65888663986&index=187
I tried drawing an architectural thing. I'm not good at it, but hey, gotta learn eventually! (I guess. Come to think of it, most people NEVER pick up this skill and turn out mostly OK.)
