I stitched a photo and there are some areas that didn't turn out so hot, I have spent many-a-hours in Photoshop [7.0] attempting to fix the seems via contrast, lightness, brightness, hue, saturation, but to no avail. I need someone with a greater depth of knowledge in Photoshop than myself to please share their wisdom with me on how to fix it. I have spent a decent amount of time in Photoshop so I am not a complete noob but am definitely no pro.

Also, feel free to critique my shots as well and offer suggestions for improvement. It was taken in Isabel Pass, Alaska with a friend of mine who is sponsored for riding snowmachines. Thanks guys.
