There are times where I see the images and change my text as a result. Sometimes it's mundane (I said "left hand" and Mortze rendered it in the right hand). Sometimes I had a mental picture of what's happening but Mortze's actual picture is much better, and I change my text as a result. Sometimes I name an ancillary character, but when I see her, I feel that a different name is better (or, sometimes Mortze suggests a different name). And, sometimes, when Mortze creates the model for a character, she's so compelling that it forces me to make more story for her.
A few examples of that:
Serena in Saving Chloe. She was just supposed to be in one scene, but she was so striking that I added 2 more paths for her in that game and eventually wrote a whole other game for her.
Jen in Life Changes for Keeley. I added her scene late in production because I wanted to balance out the two paths a bit. But I liked the model so much that I brought her into the Elsaverse and made her the eponymous character in Chasing Beth.
Also, when we were getting near the end of Saving Chloe, we started talking about what we'd do next. Mortze sent me the image that plays after the credits, and I liked it so much that it lead entirely to Darkness Falls.
So, you can definitely say that my writing has been inspired by Mortze's work.
However, there have also been times when, for one reason or another, Mortze's image(s) didn't match my text, but I chose not to change the text. The most recent occurrence of that happened in Writing with Tara.
