Race/Class: human warrior
Character is Chevenga
With a human for his main, he's given you more leeway than any other race for decoration, but at the same time not much in the way of focus. That said, there are a number of simple decorations you can make with some basic art skills. A bit of cutting, some spray paint and homemade stencils can whip up a bunch
made of cardboard or foam pretty quickly. I'd go with the latter of the two myself, though either would make great wall decorations.
In addition, here's
a link to his character. I'm not sure what kind of inspiration you can draw from it, but it's worth a shot. It appears that he's only transmogrified(changed the appearance for customization) of one of his items, the sword. That tells me he likes the look of it. Here's a 3D look at it in case it inspires something for you.
Other ideas he may get a kick out of:
