"Qualified" - 4 points

1) Focus/Sharpness - Although focus seems to be correct, the image doesn't "feel" sharp...perhaps the data is a little over-stretched?
2) Composition - Yes
3) Star Quality - Yes
4) Processing Skills - Yes - BTW, in a case such as this (False color Ha), it is acceptable to go ahead & punch up the red. I did a midpoint move on the red channel, and I think it really helps to show off the surrounding nebulosity. (I'm guessing you "toned it down" just for me ;-)
5) Exposure/Depth - Yes
6) Technical Bonus - N/A
