307259 Simple Flash Banner Ad

I need some minor modifications to a flash banner ad. I have already designed the layout in photoshop but need some "realistic", "subtle" and "tasteful" modifications made to it within Flash. The banner is attached in this project. Basically, I want the horse on the right's eye to blink occassionally and I want the horse on the left's breath to slowly and subtly breathe out (think of being able to see a horses' breath on a cold day). This banner will be visible throughout the site so the animation will be minimal and tasteful. The eye will blink every 5 seconds, the horses's breath about every 7 seconds. I want the effects staggered and very natural looking. The breath will be semi-opaque and very natural and almost look like smoke in the air, very minimal. I imagine that effect will be totally created in Flash. The eye blink effect will probably have to be first mocked up in Photoshop or image editing program to recreate an eye closed image over the top of the existing image. I would prefer the eye be in 3 stages, open as is, half closed and closed so the transition is more natural looking. Anyhow, I have graphic design experience and played around with it a bit and wasnt happy with the results and want to spend my time working on other stuff. This should be fairly easy, but I dont want anything cheesey or too fake looking. Realistic and minimal is key here. Thanks!
