@ChloeGreenbergArt i think your textures and paper cutouts work quite well actually, but it's masking some other things in your art that aren't quite up to a professional level. The style is fine, the storytelling, and composition need some work (in my opinion).
if you want a real assessment- here it is: Many of the images seem somewhat bland if you just sketched them out. There isn't a lot of actual story telling going on and the compositions are a bit static. This work should be done in the thumbnail stage and you would see that it just isn't holding up that well.
i think the style is actually what makes them look as good as they do.
I hope that doesn't sound harsh, but it's something to really look at. lets look at this image for example. Like Will Terry says,- say the concept out loud and see if it's interesting - "hey, there is a girl in church and she is raising her hand". now, does that concept seem like something that is portfolio worthy? It could be, but you really need to lean in on where the tension would be for a scene like that.

hope that makes sense. I look forward to seeing how you adjust your storytelling to fit this already cool style you are working on. : )
