Hi there! First of all: your assets are awesome, I am really looking forward to what you are creating!
About your questions: as a developer it is always hard to find assets that match in style. So if I may express one wish it is to maintain compatibility to the heroic asset series. Even if it will be for another genre, chances are that there are useful assets in the other, so the buyer has a wider range of assets to choose from.
Thank you and keep up the great work!
Daniel
