I have been playing with Gemini for a while, but wasn't aware I also had Google Flow attached to my subscription. Decided to play with it and gave it a sketch of my own (first image), a character for it to pose.
Results were good, yet composition was off. I them told it to explore a few character rotation poses, and it resulted in some minor inconsistencies I was able to tweak on Sketchbook Pro.
The final image combines both the Flow's output and my own art and coloring, complimenting that first image to create a complete pinup.
