I see this cactus everytime I go down a certain road and finally did a sketch. This is a Saguaro with multi-arms. It seems to me I see these many-armed Saguaros more in the wild. All the black spots are probably nesting holes for birds although some are just bad spots from birds pecking at them.
I did the initial sketch in ink and was tempted to leave it that way but I just couldn't.
I just had to add color.
Happy Cactus Monday!
