No worries. I like your stuff quite a bit. I'm working with programs that have limited palettes (one has a user-definable 64 color palette, and the other has about 840 colors. So I end up having to redraw a lot of things. But one thing I've noticed is that some of the themes, like your Japanese them, have very different palette colors (which is awesome because it's pretty). But I am willing to bet money that if you included palette swaps of some of the assets in each pack (like the bamboo platforms and a tree from the ninja pack colored to match the Mystic Sakura, for instance), then you'd probably sell many more assets. Like it would enhance the value without being a lot of work for you (hopefully).
