It's always nice to see artists with a distinctive style. Especially when they are creating pieces that could easily fit into the world you are developing.
I went looking for ideas along the lines of "Town Guard" and I found the blog of Martin Reimann.
A lot of the work I'm seeing over there could easily be integrated straight into my Walkabout setting.
If the crowd-funding is successful later this year, he might be someone I approach to produce some illustrations for that game setting.
