I should say I have nothing against the premise of the business - if it provides livelihood to traditional craftspeople (or just talented artists of any kind) more power to you.
However, you are not making it easy for me to believe that you have the artist's best interests in mind. Let me count the reasons why:
1. Not a single individual artist or craftsperson is mentioned anywhere on the site. I don't know about you, but when I hear the term "artist," I think of an individual with a specific way of looking at the world. Absolutely every Indian artist and craftsperson I know has a desire to see their individuality recognized. You claim to be sourcing artists but you don't recognize their personhood anywhere. That's rather strange don't you think? It's possible that during the portraiture itself a bond is established between the representer and the representee but that's not the case on your site. It's an easily added feature if you're serious.
[EDIT] - as another commenter pointed out, there's a byline for each artist so what I said above is flawed. I still think you would be better off highlighting the artist's vision in more detail. For example, did artist X make the portrait in style Y - Suprio for Ballpoint Magic for example? If so, why aren't the portraits signed? Why choose to anonymize them at every stage? Otherwise it looks as if you are choosing to stroke the vanity of a western/affluent Indian audience.
2. Every Indian state and linguistic community has artistic traditions. Madhubani is different from Company painting is different from Mughal paintings. None of these traditions are even mentioned. In fact, there's no evidence that any Indian aesthetic tradition matters at all. Instead, what you have are generic categories - "the vision lure" - without connection to artistic traditions of any culture.
3. Then there's the origin story - "the idea was hatched when so and so were sipping coffee and discussing the works of Raja Ravi Verma in the historical city of Udaipur." At the very least that suggests an intimate connection between Raja Ravi Varma and Udaipur, especially if you aren't Indian. Except that RRV lived out his life in Kerala, far away from Udaipur and from a very different artistic and cultural milieu. If you had started the story with Tantric paintings [1] that are still produced anonymously in Rajasthan (just like your artists) I would have taken notice.
Suppose I went to a cafe in Stockholm, discussed the "da Vinci code" with a friend and decided to start a business in Italian greeting cards made for cut rates by unknown artists in Neapolitan neighborhoods (in between assignments for the 'ndrangheta, if you want to add some mystery to the whole process)- in what way would that be beneficial to European art?
