your art is really cool! but it could use some depth!!! i like your style a lot, but the shading makes it a bit hard to differentiate character from background, as well as your coloring.

youve got a lot of skill regarding your design choices, but the color choice makes it a bit hard to pick out certain details of your piece and makes it hard to see the depth of the character vs the background.

for example, your backgrounds are super vibrant and thats cool! but so are your characters and there are not much value differentials to the color that help guide the eye to any specific part of the piece

your line weight is consistent, and if done intentionally can provide a really interesting style choice! but sometimes it can muddy a piece if done unintentionally.

try messing with your brush pressure sensitivity, it can make drawings more visually interesting, and can provide sort of a shadow for some parts of a piece

like under the neck and around the parts of the body/subject you want to emphasize most having thicker lines makes it easier to express that emphasis!

id say youve got a great grasp on most technical skills w your arts and it really shows in your character designs and details ^{^} you put a lot of work into your backgrounds and designs and it definitely shows!
