Wait until you notice problems, this will help you pick a new camera.

In other words, I think you should wait a while.

As any number of people will tell you, the 'eye' is more important than the camera.

[Like everyone else, I too suffer from 'gear envy' sometimes.]

There's nothing wrong with your pictures that some post-processing won't help.

Personally, I usually use Gimp - which is free.

You can find great tutorials at MeetTheGimp.org - also free.
