not giving you crap, it's just a reaction. The color and angle is better on the first one. They're pretty similar pictures, if you had said these were taken two days from eachother, nobody would have doubted you. Unless you seriously buckle down in some way to achieve a certain look or goal in your photography, 6 months isn't too long in the grand scheme of things.
For most people, I would say about a year, and if you don't see improvement over two years, than you're not trying hard enough.
For example, In my situation, i've got a 5 year goal. Where if i'm not where I want to be in my Photography by 2018, than I need to seriously think about what I'm doing with myself.
