Weekly practice

So, these show a lack of form understanding and attention to just the outline which is super normal for beginners, I suggest you to keep doing these but add a time to practice shapes in 3D spaces like one point perspective or two point perspective, if you don't know about them, be sure to search online and watch YouTube videos about it, that kind of practice will build your mind to see the shapes, not just the outline and will improve your observations greatly, don't forget to practice daily, consistency beats perfect practice once in a while, every day, and have fun.
