Although playing with color and tone is fun for your own pictures I would suggest maybe try and go overboard next time.. There are so much more cool things to do with PS! Good luck author!

very Andy Warhol.. and very well done (this would look great on a side of a building.. or a floating center piece in a restaurant less is often more....good luck

Love it ... I have to agree with Mossy and Dan ... nice replication of AW's work. Love what you have done with the eyes as well.

I think there is creativity in treating the eyes differently and in making the great color choices, not to mention the overall concept. However, having all the images facing the same way would be more Warholian and compelling IMO. (BTW is the title an allusion to Warhol's 'Mao'?)

I like the "Warhol Pop Art" effect. Nicely done! Sometimes, simpler is better.

I think that Photoshop requires a little more imagination, a little more creativity, no point to set anything !
let this be a guide :
cut - layer it - transform - insert - create - adjust - and prepare for critics
