These are some really great 30-second gesture drawings! you made a lot of emphasis on how the drawing feels and really captured the motion. Do not worry too much about accuracy when it comes to 30-second gestures - the main goal of quick sketches is to quickly depict/summarize what the message/emotion/story the figure is saying and your ability to convey this message to the viewer with few but meaningful strokes. Keep working on exaggerating your lines especially your line of action. Awesome start dude.
