Unless you're stood stock still unnaturally for etiquette purposes. And who wants to spend all their time drawing figures saluting? No. That line should bend a lot. In fact, a lot of the time, it should bend more than a human's spine could comfortably bend. The purpose of gestures is exaggeration and simplification of the complex nature of reality. An exagerrated, impossible pose is infinitely more visually interesting.
The other problems with your figures is that you're drawing the outline of the figures. Or, a percieved outline, which is very flat. Gestures should be composed of round masses that exemplify the lumpy nature of human anatomy. You're building a person, not a silouhette. Vilppu's drawing manual has more (better) examples than I can provide, and he shows how to progress from basic flowing forms all the way to shaded sketches.
But even if you know all of this, perfectly absorb this information and do your best to apply it, you will not suddenly make good gestures. You need mechanical skill, which can only be attained by drawing for a very long time. We all have a long path ahead of us. Fortunately, the most important stops are in the first stretch, and those stops are enough to produce art that can enrich your community.

God be with you both.
