First off, thanks for the update to MSFS. The airport gives a good feel as you're really there. The surrounding area is detailed well, except for the middle of the airport and ramps. There is a issue with the taxiway between A5 and A. The ground is uneven and you can actually see it in the sim and the 2nd picture for the preview of KBHM. Overall, not bad but it needs some work.
I fly out of here, and used to work out of this airport, too as a commercial aircraft fueler. The basic idea is there for this airport. The big items are there (terminal, hangars, garages, FBOs). Are they the best models? I wouldn't say so, but I can't argue with wonderful performance. I spoke with the dev and asked if he could repaint runway 6/24 since it was repaved w/in the last few years and is now a jet black color. He said he is going to do that, amongst other items on his list to fix. I think that this could be a 4 or even a 5 star airport for the price if the dev brought some additional detail to the airport, like modeling the road leading to the terminal, Terminal/FBO signage, custom taxiway signs, etc. If you had this for P3D, expect the same level of detail, though I do think this scenery deserves some additional work as mentioned above.
