You already have a good answer from LUCYMORAES38, I will just contribute with a tip on the specific subject you tried to draw.
If you had no problem with the dragon head (usaly a sphere with a alongated box in front to depict the jaw) and no problem with the helmet (usaly a cylinder with half sphere on top), maybe the problem is the relationship between those forms.
Maybe you trying to put a too small helmet on a bigger head (or small head to a big helmet).
Maybe the helmet are trespassing some feature of the dragon and you are not seeing it - just feeling the problem.
Are the head and helmet vectors aligned?
My advice is to try simpler forms to the head and the helmet, I think you tried one step ahead you should.
Just an insight, maybe it's not the problem at all.
Hope I helped some way.
