your both right.
the left side is way too dark and the right side is way to bright.
add a few gradient maps and some brushes and you have a pretty good sig.
ermm.....7.8/10
Save as a .PNG, you won't regret it. As for the sig, It really could use some more work on the overall quality, it just looks blurry and fuzzy, fix that and then I'll see what else can be fixed.
well you still need to work on qaulity.. but its alot better than your others.. the left side is doesnt suite while the left side really does... try adding a warming filter.. more blending..
