N scale steel mill massing study

While we're doing "massing studies" (see previous post on the pulp and paper mill) I took a look at the site for the West Seattle Nucor steel mill on my new five inch wide addition to the N scale layout. I think it's going to work out, although the site is ridiculously condensed for a steel mill model. The back track will be for scrap in (mostly in gons), the middle track will be for the shipping department (mostly gons and bulkhead flats) and the short front track will be for additives in and bag house dust out (mostly covered hoppers and covered gons). All tracks will go into - and be covered by portions of - the building(s).

Here's option 1, from three different perspectives:

It might be a little tall, considering the hill behind it (although that could be fixed by putting a backdrop between it and the hill). Also, this shows the additives and bag house track out in the open, but they probably should be covered.

So, here is option 2, a little longer and less high, from two angles:

I think this second alternative seems better. But it doesn't look complex enough, and we still haven't covered the third track for bag house dust and additives. So, here's alternative 3:

I like it, for now. Although it might make more sense to set up an overhead crane on the left, between the first two tracks, to symbolize the movement of scrap in and product out. Another day we can try looking at that. Let me know your ideas on all this...
