Hey, so I ended up deciding to support your work, and have been purchasing the backgrounds as you've been releasing them.
I've purchased this, also, since you mentioned 4 directional walking animations. That said, if I was to use this, I'd need the battle sequence animations to be 4 directional as well.
Since the animations can be flipped horizontally, that covers both left and right. However, I would ask you to release an updated version of this with the animations, for battle sequences, for front and back as well.
It'd be a good idea to give a guide as to which images are supposed to be part of each sequence, as well.
Otherwise, I just want to say that each image seems well done, and I love the art style.
It's also appreciated that you released portraits to go with this pack.
I look forward to your reply and seeing where things go for the future.
