Hi!
It's very difficult to explain this over the internet, so I recommend Googling some tutorials online. Also, there was a book I checked out at my local library YEARS ago, but it taught me so much about drawing dragons!! I actually became very, very good at it!! The book was called "Drawing Dragons: How to Create Fantastic Fire-Breathing Dragons" by Sandra Staple. It is a very helpful book, and I HIGHLY recommend it!! :)
Best of luck, and happy drawing!! :D
