Caricaturist gives prize for advice

Hi, Friends!

I've been working on a collection of caricatures of great historical figures.
Now, I need some feedback about the drawings and some advice about some options of the business that are still open. So, I prepared a brief presentation of the ideia, with some few direct questions about it.
For those of you who are willing to help me, here it is my caricatures presentation. It will take you just 2 or 3 minutes.

Also I will draw 5 free prints for those who participate!

I would be most appreciated if you give me your advice! http://www.ukbusinesslabs.co.uk/foru...icon_smile.gif
Thank you!
