hello,

This is my first try at editing.  I rather enjoy it so far.  Ive got along way to go with lots to learn.  I hope you enjoy, and I would love to hear any comments or critisizms on what to improve on and how to get better.

Thanks for looking.

looks fantastic, but i'll get harsh for your learning experience 

back photo look good to me, the plane is a little bright if you used brightning and contrast tool and made it a little darker would be good. Also something elce you could do is (if your useing a more recent verson of photoshop) go to Adjustments then color match and select the background it would fix the coloring. I cant remember the exact steps as i dont have PS open as a reference. Now for the jaggies, make a layer mask (remember black covers and white reveals) and paint along the edges useing black with a VERY soft brush it will make it look smooth.  Thats my 2 cents, hope it helps
