Sameer I use a bridge camera Canon SX30 now I get reasonable shots Which software do you use for editing try Light room. I feel that there is nothing wrong with your camera it is your editing.
Thanks all, u made it easy for me
I would invest in lenses first. I started with a 450D and really notice a difference when I bought better lenses. That said, I have gone to a 7D and I notice a difference there as well. I'm happy with my choice to buy glass before the body however.
