I'd say, develop a good taste first, even if you can't achieve it right now; for whatever reasons. Research a TON.
That first example is just plain horrible, it's technically excellent, but it just leaves a bad taste in my mouth. Trying too hard, overworked and fake.
Those two VOGUE images are great.
I am still learning myself, and while I am still bad, I am assured that things will progress if I keep on doing cool stuff like editorials, model portfolios, look books, catalogs etc.
That image of yours is very nice, let it be and keep on working on next job, and try to do your best there. Things will progress, I can see that right away. There are guys/gals here in the forums, but also out there, that will never get it just because they never develop good taste, and just want things done instantly and there is just no substitute for WORK.
