I have another similar piece of art I gave to my sister which is stippled, a road between two mountains…updated

Update:  The cactus is Yossarian…

“How easily we charlatans take advantage.  Its wonderful, the attraction, on the feeble minded of course, the continuous motion, if they just let themselves follow it.  Of course you could stare at it till doomsday Doctor Watson and not be affected, still it might make you a little drowsy, like the white ribbon of of the road at night when you are driving.  The ribbon is smooth and unbroken and the road goes on and on, round and round, with the same winding and winding and you’re tired and drowsy.  Let the road come into you as it were, the long road, the smooth road, the road to sleep, sleep…”

The long and winding road that leads to your door
Will never disappear
I've seen that road before it always leads me here
Leads me to your door
The wild and windy night that the rain washed away
Has left a pool of tears crying for the day
Why leave me standing here, let me know the way
Many times I've been alone and many times I've cried
Anyway you'll never know the many ways I've tried
And still they lead me back to the long and winding road
You left me standing here a long, long time ago
Don't leave me waiting here, lead me to you door
But still they lead me back to the long and winding road
You left me standing here a long, long time ago
Don't keep me waiting here (Don't keep me wait), lead me to you door
Yeah, yeah, yeah, yeah
