Before - After
I mounted the Stormtalon's "stand up" and it looks great. But not as great as I wanted it.

It just seemed to be a big green flyin' brick block with wings.
Even the highlights weren't enough to make me think that this flyer wasn't just another Space Marine kit.
My reaction was just... "Meh."

Then, the good idea came when I added the missiles pods.

All the weapons in my DA army are painted in red. On first, I only painted the missiles.
But when I added more red on the missiles pod, the Stormtalon just flashed in front of my eyes.
That's what we call the "Wow!" effect.
