Hello, good job! Personally, I would say that exaggerating the line weight a bit more would give a better effect overall. The line directly below the lid should be just as dark as the one below it because of the lid in my opinion. The tapers on the first one look fine to me. Besides the line work, you seem to be applying orthographic projection on your drawings, which is fine if it's the look you're going for, but it does make your drawings look flat. I believe learning perspective will definitely benefit your art, as it will add more depth. So I recommend continuing this course, since it will teach you perspective in the next lessons, after the shape lessons. If you don't know it already, I highly suggest looking at the drawabox course, it has helped me hugely in understanding 3D space. It's challenging and heavily reliant on discipline, but I'd say go check it out first to see if it's worth progressing in for you. I wish you the best on your artistic odyssey.

Hi, excellent work! In my opinion this drawing has applied the elements presented in the video very well. The lines are also very clean. For the glowing, what makes the original appear like it's glowing is contrast. The character is very dark in value overall with solid black shadows for contrast to the dark gray skin. The mouth is very bright, contrary to the rest of the body, thus giving the impression of a glow, this appearance is further enhanced by the lighting along the teeth. For this reason, I believe you did a decent job at achieve the glowing look with only lines, since teaching full shading wasn't the intention of this video. Although, I do think that you could've added darker lines on the contour of the entire head, just to make it more visible since it's kind of hard to see from afar, the head is fairly important for people, so making it appear more important would maybe look "better", just a suggestion :). This is just my opinion, I'm not a pro, I'm an amateur who's also trying to learn from Proko. I wish you the best on your art journey!
