In this GFX the marbles represent the “positivity” and the girl has lots of it in her basket, so she’s sharing it in the otherwise grey and rainy world.
EDT: I’ve looked into it and it turns out this technique is called “colour splash”
Because to tell you the truth. She herself isn’t happy at all.
The big grin is just a cover up. Still she devotes her day to making other people happy.
EDIT: i made this all up btw. It has nothing to do with any actual roblox player
I like it. However, if you’re willing to improve your graphic designer skillset, I would recommend try to make the floor blend in with the background more because it currently looks like it’s floating.
I actually really like this GFX and find it quite unique. The greyscale mixed with the vibrant colors gives it a deep theme not commonly seen yet. Props to you.
