Hi, Friends!

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

I would be most appreciated if you give me your advice! Your comment about the site will also be welcome!
Thank you!
