Hi gameover,
That does look a little small. The picture below is mine. Sorry but can't figure out how to post it right now, you'll have to click on it. it is over in the abecedarian proxy thread. I made it based on plans for one from Fox Field in Lancaster, CA. and it is to scale.
I think your looks great it is just a little under scale. Like the picture with the Camaro on jacks
