I have been drawing a lot lately (everything is unfinished, that's why I don't upload anything xD), and I realized that my dragon has some unrealistic things that I don't like, and sometimes I find very hard to draw, so I'm considering to re-design those things of his head. So I doodled this today.
One of the things that I MUST change are his two little horns over his eyes, I drew his skull and tried to add those horns, but they looked pretty unrealistic, I don't think those horns can grow in that part of the skull...
So, now they are between his two principal horns.

His spikes were another problem, I designed them like they were big scales over his body, but again, they doesn't seem to be realistic for me, I have no idea of how scales of that size and form could grow over his body, and in certain poses they are exremely hard to draw for me.. so, I'll change them to sharp black bones over his body, like I did in my first designs of my dragon

And I'll probably change the look of his "normal" teeth to this one, I think it fits well a crocodile style teeth in a perverted acid black dragon, and in my opinion, he looks better :D

The rest of his body will be similar, a large, skinny dragon

seems like I'll need to make a new reference :(!
