Dedushka Lenin :)

I love this picture.

Along with the dude behind me, I find this supports the idea of commodified life and all that stuff.

...

There's nothing wrong with a bit of minimalism. Sure it doesn't have variety but that's the point of using repetition as a technique, literally the image is repeated until it has no meaning or value (the end hints at a possible unification of the image until it doesn't look like Lennin anymore.) I think that is what you tried to get across rather than difference within repetition by using color or something else.

Whaat?

Why would you waste a canvas with this? Why not add some kind of color progression? Something in a monochromatic scheme, or even an alternating color scheme? But it's just boring and covered in over AND under spray. Come up with some substance, then use canvas.
