FRONTIER WORKS: FUTURISTIC HEROES AND BGM

I'm looking at this and thinking, I like the illustration style.

Question to those that have this and other characters packs...
Which ones are similar in style?
This character pack has essentially 8 characters. Some of which I would not be able to use.
However I would buy it if there was another character pack that is similar or perhaps *wink
another character pack can be made that will compliment this one.
My game is not a future one but the character images look robust enough to use in my fantasy style game.
The reason I can't just go with this one is that there are not enough characters for me.
I have 14 male and 4 female as characters choices.

Comparing this to an artist to do images, this is way cheaper. But I need more character images, sprites and faces.

Thanks.
