There's a lot to comment on for this... Not all good. Please take this as constructive criticism.
Don't use artists' color profiles for colors. They can be printed off-color, then re-scanned with the wrong color settings, and turn out far different than intended, and also they can just be wrong from the person that created them.
Use them as inspiration only. Use wp.scn.ru only as inspiration and then find OTHER references to that plane/profile and build off of them.
Second, there is a lot of inaccurate stuff on that skin.
Not only are the colors not quite right, but you haven't put any on top of the wings. The yellow nose isn't the right shade and isn't quite perfect, and the side mottling is rather garish and "hard" edged. You copied the profile rather closely, but sadly that profile is not accurate. It's just a general one to show an approximation of what the plane would have looked like.
The mottled spots would probably look a bit more like:

Other skins from that other game which show side mottling effects which would apply to your plane:

It's just hard to come up with an example on short notice for this response, otherwise I'd have included it here. The best I can find is this:

To help with the colors, you're going to want to take a look here:
http://www.ipmsstockholm.org/colorcharts/colorcharts.aspSpecifically the sub-section on German colors is here:
http://www.ipmsstockholm.org/colorcharts/stuff_eng_colorcharts_germany.htmThis will give you a much better starting point for colors.
Also, there's just a lot of detail missing on the skin. The fuel triangle on the port fuselage, and things like that. You also have a very faded and fuzzy squadron emblem on the port nose. You'll need to clean this up a bit and also put it on the starboard side. Both sides should face "forward" (i.e. mirrored). You also left a chunk of green on top of the nose which ought to be yellow, at least according to your profile.
And the left and right "wing lights" are just wrong as well. These were stationed on the front "corner" of the wingtip, wrapping from top to bottom.
I think it's fair to say you have an interest in skinning, and that's good. It will keep you going. The first skins are always the hardest because you're learning the ropes.
I think, however, that you need to do a lot more research to "get it right" before you submit a skin.As a foot-note, I wouldn't bet on this, or any other newly-submitted skin being in-game in time for the upcoming scenario. Chances are due to the turnaround times involved that we'll be using only the existing in-game skins for that scenario. BUT, if you get a finalized skin in-game it will be there for future events, further down the line.
