The most controversial drug of the 60's and 70's´s was undoubtedly the L.S.D according to its initials Lysergic acid diethylamide. Social groups like the Hippies at that time achieved an effective connection at the artistic level, achieving high quality musical pieces, paintings, clothes, poetry, whatever was related to art, anyone under the effects of this acid. He achieved the plusultra, or as the believers in Hinduism preferred to call it, "the nirvana".
Today it continues to come to light that the L.S.D. was an American military program with warmongering purposes and domination of the psyche of any soldier.
It is enough to think when I wrote the word nirvana to place a theme of this popular band of the 90's´s

Step 1: When I plan to draw something I usually start at the top regardless of the order of the lines.

Step 2 after finishing part of the skull continue with the rest of the ocular cavities and then I started to draw the jaw.

Step 3 to demonstrate that it is a handmade drawing. Notice what the typical points and intersections of a construction look like in vector design programs.
