It's very hard for me to parse what's going on in Blackpaintbowser's screen. The wall-blocks are individually pretty--not super realistic, sure, but Yuureikon shows that that kind of abstraction can definitely work. But...nothing else about this screen does it for me, unfortunately. The flat green background is bland, and what decorations are there just look scribbled in. The vines are too bright and contrasted to work well as background, which is...I think that's what they are? Even at the best of times, I'm not really a believer in ZC sideview, and this has a long way to go before it comes close to the best of times.
I've seen a bunch of 1 Screen Gollab stuff lately, and a lot of it is really promising! Unfortunately, I'm not a huge fan of the dungeon that Jenny's screen is from. The green and yellow and fuschia just clash really badly for me. (Maybe green to teal, or pink to red would improve it? I'm not sure.) I do want to take a second to appreciate the transition tiles between the floor crystals and the ground, they work really well. I like the wall-to-black transition tiles too. In conclusion: owls can't have googly eyes, they have to swivel their whole head around to change what they're looking at, therefore 0/10.
Joel's screen is...fine. I do like the general structure of the room, and his wall to black tiles also look quite nice! I think mostly I just find this screen a little bland. The palette does its job but also leaves the whole screen a little samey. The thicker cracks, including the ones on the walls, are a bit awkward, like they're taking what was supposed to be antialiasing but darkening the color of the antialiasing so much that it just looks like an extra coating of black.
Nightmare's screen is very green and I am not really a Mario person and I'm not really sure what else to say!
Orithan's screen is my second favorite. The mountaintops confuse me a little, they look more like fencing than like this screen or the heart piece are on elevated ground? I'm not sure if this is Cambria's fault or if there's a fix and I just don't know it. The mountain with the enclosed heart piece also bothers me a little because of the sheer vertical line on its west side. The grayish trees and grass and blue lake look nice together.
I like Twilight Knight's screen, which is such a relief, because I was worried I was being too negative up there. The lake is pretty and I appreciate how natural it looks without being blue. I like the brown grass but I can't decide if the land as a whole is stronger or weaker for being kind of...monochrome. (If it's the second one, I still wouldn't use vibrant colors, but maybe the trees and plants could benefit from being a different shade of yellow with more contrast? I'm not sure.) Ultimately I think this is a pretty solid image of a sickly lake. I voted here.
