Guessing blindly, I would suggest enabling alpha testing and/or depth testing.

GraphicsDevice.DepthStencilState = DepthStencilState.Default; at the start of your draw method.

- Painter's Algorithm: Sort from back to front, draw in that order.
- Depth Buffering: Discard pixels that would be behind what's already drawn.
If you want to know how to implement occlusion culling:
- Occlusion Queries (Z-Buffer hierarchy is a good optimization)
- Precomputed PVS and portals
