No problem. Just to note, I am not trying to be mean, i'm trying to be critical. If everyone said they were amazing etc... then you wouldn't get any idea of what people really thought, but yeah you are still learning so fair enough. Just keep trying out some different effects, I usually don't use vignetting as I said before however I do make good use of the curves and edit the shadows and highlights quite a bit to get the lighting and exposure I want.
Those two you did there are quite a bit better than the previous ones, although the first one is quite overexposed but I reckon that could easilly be solved. :)
And thanks for your comment about the Aston shot. It's not my best and I will admit that but I tried something different and people seem to like it so that's fine. :p
