Hi Jerry, I really like what you have achieved so far. I think the flexibility you have allowed yourself in positioning the buildings is the best way to go. For my two pence your could keep your new building along the rear adding your two original buildings. As has already been suggested you could put the industrial units in front of the fiddle yard. Making the bridge at a slight angle might open the layout up a little and create space for your dummy head shunt should you chose to do so.
Sorry for the late late response to your question, I don't have a website for my micro, but I did take some pics of the construction so I could put them up in future.
