Still life

Good looking models.  I think the scale is a little off, considering the size of the nails compared to the hammer and ink pen in the scene.  I'm sure somewhere there are nails of that thickness and length (larger than a writing pen) but it's relatively rare, and doesn't really contribute to the believability of this shot.  The detail in the hammer textures are good, but the wooden planks do not hold up at this close perspective.  When choosing a close camera angle, you'll need texture maps which can hold up to the scrutiny.  Check out CGtextures.com for free high quality textures of wood and other materials.
