I recently bought a Nikon D5300 as my first DSLR and I've been very happy with it. A lot of the advice you have received here really resonates with me. In addition, here are some of the things I've done to improve my use of the D5300: I've bought an ebook about the D5300. I take pictures every day to practice. I've taken a photography beginners' course. I use the Internet actively to increase both my technical, compositional and processing skills. And I'm constantly experimenting with processing my images in Lightroom.
