Grab a pencil, eraser and some paper
You can do this any way you like, I chose to do this landscape.
Sketch a circle
Now sketch up to make a comma sort of shape
Now draw the mouth and head
Time for the wings!
Draw a long curved tail
This does not look like some legs at all but we'll fix that later
Don't forget the mountain in the background!
Start to develop a mouth
Now go back to the wings
Develop the legs as shown
Add an eye shape and a flame sort of shape to the back of the head
Add details to the wings
Add some spikes on the tail
And some on the wings
So far we have this
A spike on the back of the leg
Begin to shade around the areas you think are in need of it
Add some more details here and there and your done!
