I love the work and the art stile - Do you know of other assets which fit into your stile? 

I consider builder a small RPG with your assets (have not bought yet) but need to find some chars first. 

I have seen 3d chars - but they are a bit tooo square for my taste.

I don't know of any off hand.  I'm an environment artist only currently.

Just found this asset myself and reading through the comments. If you or anyone else is looking for characters I think the polygon series from synty studios would work well.
