Luxxeon, you modelled that purple grave object without any sculpting tools, just modifiers?  I'm surprised you were able to get that kind of mesh deformation with only 50,000+ polygons. But then again, there isn't that much fine detail there, mostly large surface changes.  I really like that wooden cross, even without textures, it's clear what its made from.  If you add some small rocks and stones around the grave, and maybe a few strands of grass, then you will have something really cool there.  If you do the textures right, it could be a premium model.
