Here's a simple tip many folks forget...
When drawing or painting a full standing figure, make sure the Center of Gravity (or as a short cut, use the Head as a substitute) is between the two feet or, at least over one of the feet.
This will insure that your figure doesn't not feel like it's falling off the page.
A Pro Tip...
IF you want action in the pose, as opposed to stability, you can intentionally tip that triangle over.
With love,
