Hi Neil,
You can use all the images anywhere you want, no restrictions on any of the packages. As you own the Pro version you don’t even need to reference that the images were created using the program, although you can always give credit, it’s nice.
As for the multiple pose topic, we’re discussing the possibilities of multiple poses per character internally from time to time. We are aware of the limitations of our current system and this is not something we can easily add, as the whole design of the program came from a single point of view of the character. Currently we focus on enhancing the current experience with other features, but we also have a few ideas we want to experiment with if we have the time, but these are yet to be tested.
Please let us know if you have any other questions.
