After picking up Wynter's world, what needed to be done was preparation. She couldn't just go to that world without anything to show for it. She wanted something that could sell fast and in demand.
After experiencing ten worlds, she knew what was hot and what could sell though she wasn't certain that it would be like on Blue Planet.
That was why she was in a hurry to let her people focus on what they knew the best.
Paintings if sold well or marketed to the right people, she could earn pretty well.
With the fact that the era she lives in right now is ancient when compared to Wynter's timeline, maybe by the time she goes to the other side, she will have antiques.
These rich people loved antiques so much. That was why she had them paint landscapes and majestic animals.
Potters, she wanted them to do vases, ink slabs and other fascinating products.
