Hi! For levels, it's what you feel more comfortable with, so Level 1 is typically if you're a complete beginner and Level 2 if you're an intermediate student looking to polish their fundamentals. But you're welcome to try a hand at both if you so desire, there's nothing wrong with more practice! I like the work you posted, you've got some fun designs and use of shapes. I would recommend trying out some videos from the line section first too. Even just some line warm-up exercises would be a useful addition to your drawing practice: Tapered stroke: https://www.proko.com/s/GFZQ Warmups: https://www.proko.com/s/iu1Q Line weight: https://www.proko.com/s/Rcue

You've got a pretty solid study here, and texture analysis is always a great form of practice. For observation and shape, if your goal is to train for hand-eye accuracy, something to note here is that the drawing seems more horizontal and the main grooves converge earlier than in the reference. Everything in the reference appears to be diagonal, so it would help to use your pencil or another stick-like tool to measure out the angle of the main lines in the reference and transfer that to your paper. The Drawing Basics course goes further into this: https://www.proko.com/s/8B6Q However, this study seems more useful to practice line weight, and I would say this was successful. The note for it I would have is more on the line control aspect. There's a tendency to scribble or zig-zag back and forth, but looking closely at the reference, you will find a clean, controlled rhythm that is worth practicing. A close look also shows that the individual grooves taper in and out, which will definitely give you some good practice for weight control. I would recommend starting consistently on one side for your strokes to keep a clean rhythm, rather than going back and forth in a single sweep. Hope this helps!
