Alright!
Critique for The Jade Heart by @EbonyKaze
Confusion is the biggest issue here. You have very fun characters and a knack for capturing different expressions (both facial and body), but without clarity, it's hard to make them shine. Readers love mystery, but they hate to be mystified. You can't bring people to care about the story if they can't follow it.
Camera Angles
I've plugged this link before, but here it is again. The 180-degree rule!
This episode has Mimi on the left, and her sister on the right in the top row.
Then in the second row, suddenly it's her sister on the left, and Mimi on the right.
That breaks the 180 degree rule. I strongly recommend following the rule to reduce confusion. Sometimes you can get away with it, but since clarity is the most important thing here, every little bit helps.
Visual Clarity and Setup
Sometimes, the panels aren't showing me enough information to understand what's being depicted.
In this episode, for instance, you have the "blragg!!" panel. I know it's supposed to be showing the demon falling, but I only figured that out by reading the next page. It would be much better to actually show him fall -- show how he loses his balance. Show his feet stumbling backward.
Why is Mimi saying he's gonna blow -- if he wasn't gonna blow? I realize characters can be confused, too, and it's possible for someone in that situation to THINK a demon is going to blow even when that's not going to happen. But for clarity's sake, I think it's better to omit that kind of stuff. Mimi's confusion does not seem to add anything to the story.
Where did the body of water come from? Was it always there? An establishing shot of the location would have helped a lot. You know Chekhov's Gun -- if you show a gun hanging on the wall, you gotta fire it. The inverse is often true as well: to fire a gun, first you have to show it. To make a demon fall into the water, you have to show the water first, or it feels like a deux ex machina. You have to set things up.
...Unless the demon blew up and became a large body of water... in which case, you need to show that explosion/transformation.
Visual Progression
I really like what you did in Chapter 3 pages 2 & 3. You start with the shot of the entire region, then zoom into different areas, including the school exterior; then you show the school interior. The camera is basically traveling from high up in the sky, floating down into different areas of the island, to the school, and inside of the school. That's a very logical progression of location changes. So that's a positive example. ^_^
Then on page 5, I'm suddenly confused again. Where is Mimi? Where is this room with the pink floor? Why am I suddenly seeing the school exterior again? We're changing locations within the school building, so it would make more sense to use an establishing shot of the school interior (maybe the hallway just outside the classroom, or even a wide shot of the classroom). Showing the exterior between those scenes makes me feel like the character first went outside.
While we're discussing page 5, the "Shinkk!" is the sound of Mimi opening the door, right? I think it would've been helpful to actually show her opening the door. You could even combine that with the establishing shot: show the inside of the classroom, and someone (Mimi) opens the door, cutting off the teacher's line.
Fun exercise
Try turning all of your text into dingbats -- including onomatopoeia. See if your pages still make at least some sense. Get someone else to check out your dingbat pages for you if you have a hard time judging your own work (it's VERY hard for me too). If they can't tell what's going on without the text, that means you need more visual clarity.
Now, not related to clarity...
Lettering
Proofread your text! Lots of spelling/grammar issues -- "your" when it should be "you're," "use to" when it should be "used to," etc.
Also, consider using a lighter color for Mini's thought boxes? The dark green is too dark for me, and it's a little hard to read the text on it.
PLEASE consider keeping your line height consistent! It's weird to see the text all squished up sometimes, and very widely spaced out other times. Keep your font size consistent, too. Only make them bigger or smaller for shouts, whispers, etc.
I think I've covered the most important issues. I hope this has been of help to you! Feel free to discuss anything I've said.
