...Other things wrong? Sure! There is no ballast on the track. The two engines have the same number. There is no engineer in the locomotive. The engines are operating without a headlight. There is no vegetation on the hills...wait a minute, it could be Nevada! The lead truck on the second engine is not on the track....just kidding. :grin:
Now see, I just call those things self criticism!
No ballast, well that's just a work in progress, not necessarily something wrong. Now if you'd have ballasted with HO ballast instead of N scale ballast, that could be something wrong but you would have needed a much higher resolution picture to notice... just like the engines with the same numbers. I know the colors but I can't even make out the Union Pacific lettering on the side much less the numbers.
No lights on and no engineer - Heck, that train could be stopped cold in it's tracks with the engineer using the Jon... or it could be backing up.
No vegetation? That looks just like lotsa places I've seen!
Which brings me to that final point, your overall presentation is excellent and I think it would pass all but the most scrutinous eyes.
However, if your exhibiting it at a rivet counters conference, ye best look out!
Now that you've shown a view from higher up, I think the thing that bugs me the most is the distance between the tracks.
