Outstanding for a first skin, well done.
My nit-picks with it so far are:
Your yellow 7 looks very pixelated and blurred. Maybe that's to do with the distance at which it is being viewed and your graphics set up.
This brings me to a side point. Have you got the Hi Res pack installed? Having that installed will give you a massive improvement in the way your computer displays rivets and panel lines on the skins you're using in-game.
If your computer is not up to the task of running the Hi Res pack on a usual occasion I suggest you do what a squadie of mine suggested to me when I started on my old computer.
Install a seperate version of aces high and name it Aces High Skin or something. Set up your graphics (at the splash screen when the game starts, not in-game) to the maximum your computer can handle (even if it only runs at 6 FPS or whatever, you can still get screenies) and install the Hi Res pack.
The trick is, every time you start up the game and change graphics settings the game rebuilds the graphics cache which takes a long time and would get very tedious if you had to do that all the time. Do all of your skinning in the AH Skin directories and take your screenies there and use your regular copy of AH for playing.
The second is that you have a fairly dramatic cut off in dirt on the underside of the fuselage immediately after the rear section of the wing joins the fuselage.
I've never seen marks like that before and I would suggest that the aft fuselage could do with a few flicks of mud and assorted dirt and what-not. Not as severe as right behind the the wheel tracks, of course... but this is Russia, after all.
Also, you've missed a few of the spars on your canopy. The front and rear sections are white, the openable section is black.
Excellent job though, mate. Really done well.
