Of course, you could use BagginsBill VSSProp to breathe realistic life into the V4 Texture.  This is not something a newbie should undertake unless you are willing to read tons of pages posted here in the forum.  But it is well-worth looking into if you are in the mood to experiment with shaders.  Search the gallery for anything using 'VSS' and you will find excellent examples of what this tool can do.
