Hello Edsun, thanks so much for submitting your assignment! I hope you managed to learn something from the lesson, keep going! This is a great attempt; I would say definitely try to be conscious about where all your lines are converging towards. There are a few inconsistencies here and there that make the structure of your helicopter feel a bit wobbly. I'd even suggest: try drawing boxes and basic shapes first with a pencil or light pen before marking in with your brush pen! I've pointed out some inconsistencies in where your lines are converging here in this drawover. Another exercise that really helps getting used to drawing perspective is drawing cubes, freehand. If you draw 5 cubes every day, and really try to make them even and accurate, you will gain incredible mileage in drawing things like this! Thanks again, looking forward to seeing your progress!
