points I see that you might find userful:
- dont use blur tool, if you want to use it mimic a photograph or a video frame that's blurry, so it's not that random (I used to abuse it myself when more noob)
- ear positoin is too close and too high if you compare to the eye, ear starts in the midle line that cut the circle of the profile head.
- draw hair like everything else, as a mass, then go to detail it, at the moment shading is not consistent as on the rest of the picture
- that rose is gud, but it's like another image pasted in because it's way more detailed than rest of the image
- skin cant be darked with black and wee see some blacks over there, only if you mind using magenta/blues to it, it will make it more readable and beilable. mid tones and highlights are good on skin
5 the yellow light that makes the edges should have some variation in thickness - eyes third eyelid should ve visible, if you want to make them more cute, avoid drawing a closed siluette dark line around it, make it softer
- the loop epic foreshortenig is in contrast with the calm composition and stable hair, it would be better without it at all, it's doing something weird with the image border, let it rest
- background yellow light spots could be white in the inside, it would be readen as white light more realistically and it would make the yellow push less that oversaturated hair (it's nice, but maybe with more darker and less saturated parts would make more volume
kudos for cute face
