I give it a sturdy 7, you could have waited for the textures to load a little bit more at the top, although the clouds are nice.

Too bad about compression.....it really killed this pic.

6/10 Nice pic if you look at each element seperately. Nice aircraft, decent scenery, neat cumulus....but what you may have wanted to do is bring everything to-gether so each seperate element becomes an important part of the whole scene. There could be more harmony to all the different elements, they should use each other to create a story, a theme, or maybe just a "raison d'etre"..(reason for being) As well, i've always felt that aircraft shown in a pic should be quite close to the viewer and usually the primary focus of the screenshot. When all the principal elements of a pic are far away from those looking at it, the pic tends to lose impact, meaning or drama. Not to say you need to zoom right up to the aircraft on every pic, but if your scenery and secondary focal points (clouds, bridges, AI) are typical and relatively lifeless, a wicked aircraft close up using a new and interesting angle or perspective will go a long way in transforming a typical pic into a great one...

Ecko, why don't you include a few suggestions as to how he could improve his shot...(part two of his thread title) 

That's what I call advice! Great example Ecko!
Hope this is valuable advice and that it helps you, debug!
