Okay, finally back home but World of Minecraft uploads are failing me, here's the terrain:

I got yelled at when I tried to do a simplicity pack so I thought I would do a realistic pack.  Problem is, I really like a lot of the textures, So I called it semi-realistic, what you see in the screenshot is what has changed.  I would really like to change gold but I don't know what to change it to. 

------------------------
I also made a realistic tree bark texture but people building with logs that don't have the pack expect a different color, and the things they build look bad, here it is though if anyone wants it:
