Well, my suggestion is, build them above the ship! :)

That's what I do, as you're more likely looking at them from below or the side! ;)

Here's one I made a few months ago, tell me what you think of it? :D

(I'll post them separately, as it's acting funny...)

But, if you can see what I'm getting at anyway, it makes the ship more defined, and the balloons still a noticeable part, but not a view ruining part! ;)

My honest opinion...

You need to make the side balloons shorter, they stick out way too far and take the glory from the front/point on the actual ship, Which is where I believe the glory is supposed to be directed. ;)
