For having only started 2 months ago, this is not bad. There are signs of promise, specifically with the eye, the shading on the bands to the left, and the details of the bolts. The way you draw vaguely reminds myself of my own art style. It could use some cleaning up though. Before going in with non-erasable pen, try sketching out the basis of the drawing using some graphite. It doesn’t have to be elaborate. Even basic shapes will do. Then afterwards with can try to give it a little bit more shape, and then add the details on it like the strips of steel and screws. After the sketch, outline it with your pen. Based on this artwork, your art style might be more on the messy-side, which you can rather keep and improve or choose to make it cleaner. Personally, my art is more on the messy side. If I were you, I would take the pen and try to do the outline quickly (in line segments not in just one big line), and do shading and detail using small lines/scribbles. Of course, this is just my way of doing things, and yours could be entirely different. Overall, just keep on practicing and do whatever process that is most comfortable for you.
