Pit Of Vipers

This is the idea from a friend i got to do a picture based on lyrics. One of my favorite songs is Pit of Vipers by Simon Curtis, and ever since I heard the song I always pictured this. I still am not good at drawing snakes but I tried to make them as good as I could, but I think I did good on my shadings. I'm also sorry the text is hard to read in the picture; i went with red to contrast with the dark brown cliffs.

"I'm falling deep into a pit of vipers
Over me, over me and I can't break free
Secrets run deep when you're in a pit of vipers
Slithering, whispering, feel the venom poisoning me"
-Simon Curtis
