@Geoffrey-Mégardon hey there! I love your character designs! Im so glad you posted on the forum, its a pleasure to see people’s early stages and help by being another set of eyes.
I put dome grid lines over each of the sketches you shared and it shows something interesting
(The only way ive found to scale images is by screenshotting images together, i guess the width controls the size)
Its rough when you have been looking at an image for a long time, you make what seems like a huge change, but really all the variations are ….basically the same…
The middle and thirds grids are really helpful to boil down a composition and give you something firm to guide you ( grids aren’t subjective!)
Something else that can really help to play around with a comp is to separate copies of your characters from the background and from each other, and start putting them in wildly different places and wildly changing the sizes.
I really like how your background sets up the viewing space, here are a few re arrangements i made in playing, they might not work with what youre trying to do, but fun
Im excited to see what it turns into! Ive never heard of johnny space, but im excited to find out more about him!
