Something definately looks wrong here...in a previous contest, didn't you enter a shot with heat blur?
LOL, that was exactly what I thought when i saw this shot!
Despite the quite crude looking smoke I don't think the shot looks particularly edited, and im not 100% sure it is...unlike the 'heat blur' in the last one...!
There are some inconsistencies though...
1. the smoke is exactly the same diameter on all aircraft, even though the two red arrows in the background are far far behind...suggesting you were lazy and used the same size brush in PS :P
2. Despite the fact that the smoke effect is used on exactly the same model, on some of the Hawks it starts perfectly behind the engine...where as on the others its a metre or so behind the aircraft....
3. the little blob on the smoke on the hawk on the top left, it looks like you have held the brush down for just slightly longer than the rest...and as you aren't using 100% opacity it makes it appear darker...thus the blob!
4. How the feck would you do that in slew mode?????? It would be far harder than actually flying it! I havent played FS for a while, but surely the point in it is you keep straight? Not for nice curvy descents...
I could go on, but they are my main points...! Other than that though, the editing was pretty good (aside from badly drawn smoke) You managed to cut it around the aircraft so well for someone that would draw smoke that badly that it makes me think its not edited...!
hmmmm, i wouldnt like to have to say...nor is it my place to, but inspecting that pic was fun ;D
And besides the infamous smoke, its an amazingly set up shot...can see a lot of works gone into it! Well done :)
