1. You didn’t use the template
2. Top one is definitely out because it’s gonna be significantly shrinked on phones+details with the shaders these characters will go with, will end up just looking weird.
3. Its supposed to show your own character so goku is just a rip.

your top one I might use, it’s not like the others (its not meant to be like, a collage of characters, but rather a portrait-ish thing of one or two characters posing or something)

goku isn’t OC so can’t do that sorry tho

did you export it as 1920×1080?

unless you edited it afterward then its the proper size

other ppl are sometimes exporting too small so they’re doing it wrong

my guyyyyyyyyyyyy
that guy i feel bad but
you didn’t follow the guide

specifically the “ankle” I keep pointing out, I want that to be cut off at the bottom
there is no “floor” in this, so-

i like this a lot but…it’s not gonna fit the flow of the other submissions
its too much like a promo banner and not a portrait of a character(s) posing together in a scene

again this is neat but, you got a lot of time (days/weeks) so pls tweak
ankles thing
no floating dudes in the bg
(the props in the bg are cool tho)
