Hello! These are lovely drawings. I think if you challenge yourself to find a small amount of simple shapes, it will be very helpful to you. Think of it in terms of constructing a house. You don't immediately start designing the fancy ceiling trim. You start with the framing. Everything else you add is supported by the framing. Try to find a simple shape that supports the overall form and build from there. Oftentimes we can simplify that shape into a circle, triangle, or square. After we have designed the base shapes, then we can go in an add details. Hope this helps :)

Nice linework! The thin lines are light and delicate. I think thicker lines could be bolder. Here’s a draw over to show you what I mean. You want to be able to differentiate thin and thick lines, even from a distance. This gives your drawing more purpose. Good stuff!

Hey there, I think these came out great. While you really captured the accuracy of the original image for all of them, I especially like the looseness of your sketch for the hand drawing. I think diving into it with a more relaxed approach was definitely a good call. Not only does it bring more flexibility to your sketching process, but it also makes it less intimidating and easier to play around with your drawing, which is useful when you sketch for fun and to bring your own ideas to life. It's important to have a balance in your routine of both art that will help you improve in skill and also art that is simply meant for fun and keeps you motivated to continue making art. I hope this is useful-- keep going, you got this! :)
