Hi Phil,
Okay your progression with this design is your choice if your just having fun and this isn't going to your portfolio then you can go crazy with exploring what works and what doesn't or you can review this thread instead of the initial image I posted in the other thread.

This is pretty awesome, what you should take from this is the placement of the lines.
To what I mentioned in the previous thread, lines and details that illustrate both functionality (Animation lines) and overall silhouette.
Hope this helps more than just you but to be honest in the past I'd do things 2 or 3 times over just to get it looking good and manageable.
