Unless you are trying to make a statement, which is fine, stay away from "artsy" designs (like on the bottom of the wings). Some will like them, some will, ehhh not so much.
That said, it is your airplane so do what you want to make you happy. Some go to great lengths to personalize thier design to their tastes and bedamned to anyone else, and that is just fine. In fact, I love that freedom. (I saw a baby blue 3 once and I think there is a solid pink one out there too, gotta love it. Paul and Louise did a fantastic job developing a unique and stunning look, a name, and I am sure by now, even a personality for their 3)
If you are going to do a solid color tail and continue the stripe forward as shown on your original design, be careful. That line intersections the empennage fairing. It took my painter a full day to figure out how to make this transition so it looked good from all angles. It is very difficult to execute as that fairing has a lot of complex curves. Most solid tail RV's bring the fusealge stripe forward of the empennage fairing and start the solid color there, not at the Vertical Stab. This is easy to do and looks great on an 8 with it's long fuselage. However, on my 6, that made it look even shorter than it really is so I had no choice in my mind.
Try rendering the design like the 8's and see if it fit's your eye. If not, what you are showing can be done, but you better have a really good painter with a really good eye or the only time it will look correct is when you look at the profile. It will not look good from any other angle, which means it won't look right from most angles. Again, very tricky to make this look right as it crosses the front part of the fairing.
Have fun. I think people really enjoy looking at all the neat ideas. Getting kind of hard to be unique with 8000 of them out there.
