I think you blurred too much and now all the shading looks washed out.
The hair is very nice, the shading and the lines are good though
it needs a more darker shade in it. Add some dark brown in and the
hair, mostly around her neck and areas where your hair gets the most shade usually.
The flowers are nice but lack detail alot, they also
look washed away from the intense blurring.
I think you should try working more on cellshade to
practice, shades and adding some highlights could really
It's a really nice wall and you did a fantastic job
putting it all together/lining it. Just lacks that color and shading
it needs to really look amazing.
Hope the advice helps <3
