It's a very good start and a good base to work from, An-225 8-)
Are you using photoshop for your edits? If so, for a better heatblur effect (which I picked up from the editied screenie forums), if you select an area behind the engine where you think the heatblur would lay, then use the "Ocean Ripple" effect, and play around with its settings until you've got that right. Then use a slight Gaussian Blur (mind you, any sort of blur would probably work) so it isn't so prominent.

If you're not using Photoshop or a program with similar effects, please disregard this message.
