We draw a rectangle, we halve it, hyphens we note where will be is sharp elements of wings. From above — it on the middle of halves, below — 1/3 halves from edge.
Now we draw the head, the parties of the head direct, ears slightly go beyond a rectangle. Now we try to draw identical curves with the friend of the parties.
Further we draw curves in the top part from wing top to the head and we plan from below ticks final points of a wing. As it is possible to see they are on the middle from height of a half of height a rectangle and at distance 1/3 from this straight line.
That it was easier, at first we draw a bottom of a body of a bat, then the part covered.
We erase a rectangle and we paint over the Batman's badge in black light.
