More drawings on my iphone

Getting more and more 'addicted' to drawing on iPhone, though I can do a better job using Painter or Photoshop.
I wanted to see how exciting can it get, in terms of drawing.
Also, I wanted to explore if I can come out with any new products for my company - Portrait Workshop..... Right now, more on the drawing parts....... target audience? Facebook avatar? Not sure yet. Quite time consuming at this stage.

More on Tiger Woods.....


Incomplete Obama....


Angelina Jolie.... I might scare my potential lady clients away with this caricature..... :D


Arnold Schwarzenegger ..... More refined now, I think.
May need to buy another drawing app to further fine-tune it and the rest of the artworks coming up.....

Explore explore explore ...... It is always very exciting, especially when there is no commission involved. I can do anything I want.:)
