I have been working on a very fun project that I want to start using for advertising purposes so prospective clients can see my own creative interpretation of their pets via photographs provided. I found a collage making web site to come up with these photo/drawing comparisons. The only downside is that sometimes I make modifications per the owner's request or my own artist's judgement and I hope prospective clients don't look at these thinking "well, why didn't she include the bridle?" or "Why is the forelock/mane like that? It doesn't match the photograph." Perhaps I am reading too much into this. Still, I've seen other artists do this and I like the concept.
