Sometimes when people see an interesting subject to photograph, they either don't get close enough or they don't fill the frame (these are kind of one in the same). I know that was the case for me especially in the beginning. I would take photos at eye level (i.e. I wouldn't crouch or lay down to get a shot, etc.). Eye level isn't bad, but the idea is to change your perspective. Even just getting low and looking up can change your subject drastically. Take this tree, for example.
I loved how dreary it looked (as it was quite cold that day), I loved the snow on the limbs and I loved the texture of the bark. So instead of shooting it from afar at my eye level, I decided to snuggle up close to the tree and shoot up.
Filling the frame can make your picture much more interesting--so next time you take your camera out, try to get close to your subject and do something unique. Even if you try it and botch it, it would be better to experiment than to not try at all.
Let me know how it goes!
