Looks like it is coming along nicely Nathan.  Like you said the text needs to be tweaked but you are well on your way.

If you want to continue with the bare metal shine for the engines, I'm hoping you can make them appear much "duller".  

However, keeping the engine nacelles WHITE may appeal more to most users, myself included.  It would also be easier for you I'm sure.

Any chance you would be willing to make that change?  

Also, on the real G-GUSI, the "wheel wells" are also painted grey.  If you are able, it would be nice to see that reflected as well.

Keep up the fine work.  Both myself and pilots at my VA are looking forward to this one!
