Very cute! I like the flat colours youβre going with. I think you can push the contrast a bit more since everything is pretty saturated as bright, you miss out on what the focus of the picture is.
I think to help with that is decide what your focus is, Iβd say itβs be the face with the yellow flowers, to push that you can brighten that area and kind of blur and desaturate the other flowers around
There also doesnβt seem to be a clear light source, I can see thereβs some light coming from the right bu try pushing it a bit more and adding shadows ( cool shadows since it seems this is day time)
if youβre going for a flat and graphic look then you can utilize a better silhouette ( a better silhoette is hooked either way regardless of if youβre going for more painterly or more flat). Try flatting your character in all black and see if you can still understand whatβs happening and who the character is, if not then try seeing how you can make the pose and action read more clearly
