I noticed that this skin has open-spoke wheels. Given the uncertainty that seems to exist at the moment as to whether any more such skins will be accepted by 777, you may want to include a normal, closed wheel cover version of the skin as well, to avoid possible delays in getting this one approved. In any event, you need to re-shoot your preview picture from the appropriate right-rear-quarter angle as posted in the requirements (see info near bottom of this post:
NEW List of Requirements for Approved Aircraft Paint Schemes )
Please let me know when you have updated the download file with the proper preview picture (and the closed-wheel version, unless you just want to take a chance on the open-spoked version and risk that delay), and I'll close this out and process/submit it to 777.
