Unfortunately upgrading the camera doesn't upgrade the techniques used to take photos, its more practice and play with what you have, different lenses, remote, tripods, flash all basic kit really. Filters can be fun, but there are so many to choose from.
As sammy say, shot in raw much more to edit and play around with than jpeg. With my EOS DSLR i shot raw but saves both raw and jpegs. Kills the memory cards, but always carry three or four of them.
Just keep playing, get your tripod and remote out and have a play at night, light painting with torches or laser pens is good fun, even black and white can change an image, although most of the time for me black and white is done after in the canon software.
i'm doing my bit for the environment, i'm off setting all them nob heads with electric cars
