HNM: Jesus I'm amazed he manage to cram so much inept awfulness into four wordless, flat, empty panels.
First off, how did she get to the top in the first place? It doesn't take an engineer to know these things have ladders or hand rungs for technicians to climb. If they're hidden from view on the other side, why is she rappelling down the rope instead of using them? Did she jump out of a helicopter? Did she lasso the 100 foot tall structure from the ground and climb up the rope?
How about the rope? It's the exact same line brush used for the windmill edge outlines. Just look at that fucking shit. He couldn't even bother using a different color or size to show how a rope is different from a windmill. He just drew the outline of the windmill, then using the same brush added another line and called it "rope". Just take a second to soak in the level of lazy that takes.
Next is the descent itself. Where is all this rope length magically coming from? The rope ends with her, yet she continues to descend as more rope appears above her. Jeph, that is not how rappelling works. The rope isn't extended as you descend, it's dropped down until it reaches the ground before you even start. You then lower yourself by managing your grip to slowly let the rope work through a descender clasp with one hand at eye level, the other behind your waist. THE VERY FIRST GOOGLE IMAGE RESULT FOR "RAPPELLING" SHOWS THIS. Jeph presents a 4 year old's idea of rappelling: tie one rope end around a fucking windmill, tie the other end around your waist, grab on with both hands and just wait until you're magically lowered. For a second I thought maybe the rope was feeding up into some winch mechanism inside the structure, but the 2nd panel clearly shows the rope was tied around the top. Can't take 2 seconds to change the line color for the rope, can't take 5 seconds for a Google search.
Then there's the fall itself. I honestly had no idea the rope had snapped and she was supposed to be falling until another mod pointed it out. There are only a couple of letter V's around the rope to show this. There is no motion to suggest this; she's ~5 feet lower in the second panel than the first yet the gap in the rope is less than 2 feet (so small that the V's almost cover it up) and her ponytail should be pointing straight up instead of continuing to point down (you can't tell if it's straight up or sideways in the third panel since Jeph just drew a sideways water drop instead of bothering to convey hair in motion). There no Emotion to convey this as both characters have the exact same expressions as the previous strip before the fall.
There are no spatial clues to show that she's falling. Her position looks like she just descended a little. The position of the broken rope is all wrong. Ropes used for rappelling are like bungee cords and have some elasticity to them. What happens when you cut a taught rubber band? Do both ends just go limp and noodley? No, they snap back violently. Both halves should be coiled towards their respective ends at the moment it breaks.
Finally he breaks the 180 rule. The guy was last seen approaching from the front of the windmill. He should be looking up to the right, left of the girl.
All of that isn't even getting into what the other post mentioned like the lazy solid color sky, the wobbly freehand windmill lines, and the lazy finger painted trees with their total lack of depth to convey how far from the ground the girl is. She could be lying on the grass with a broken back in the third panel for all we know.
This is like an educational "what NOT to do" for starting comic artist. If you need some motivational guidance as a beginner, just repeat the mantra, "I will not be like Jeph Jacques. I will take 5 seconds to study a real life photo of the subject I am drawing. I will take 5 seconds to think out what an actual motion would look like. I will make sure my drawings convey what the hell is going on to the reader.".
