Using the AI Image Editor of Deep Dream Generator

For quite some time I have been using Deep Dream Generator as my second AI Art generator. Nightcafe Studio is still the first I am going to, but then Deep Dream Generator comes next. One of the reasons of doing so is the fact that they have some additional tools which I find very interesting: One of them is the "AI Art Assistant" which helps you with creating an effective prompt, and the other one is "AI Image Editor". How does that tool work? I'll give you an example:

The photo on the left was taken during my vacation in California in 2016 near the Grand Canyon. It is in need of a bit of postprocessing with a photo editor, I have to admit.

However I wanted to use it as a start image in Deep Dream Generator, so I uploaded it to their website without changing anything.

I selected it then for the AI Image Editor and added a prompt: "cartoon drawing in the style of Boris Vallejo."

You can see the result of AI image editing on the right. 

I am still experimenting with the kind of prompt I am adding; up to now I focussed on the style of the painting (here: cartoon drawing) and the artist (Boris Valleyjo). However I figure that I could also change the light (sun from behind? Moonlight?).
