Don't worry about your height/weight. In fact, that combo can be an advantage for many moves. Don't try to mimic exactly what others are doing. With different weights, heights, proportions, and physical limitations, it's up to each individual to figure out what does and does not work.
When starting out, I recommend picking a simple obstacle and exploring all the possible movements. Use your right foot first, left foot, hands, no hands. Approach it head on, from angles, or even backwards. Doing this will open your eyes to new possibilities for moving. You'll start to see training possibilities in mundane objects, instead of always seeking the perfect obstacle.
