Not happy with your pictures? Have a watch of this video from the excellent Mike Browne.
The truth is it took me about 3 years before I was happy with my own pictures. Its not about the kit, its about the time invested. So grab the camera you have now and get out and shoot. Make mistakes, mess about. Get to know your camera's buttons with your eyes closed. Try to shoot everyday! No matter your skill level if you relax and keep shooting you will get better.
