not sure if your just going for a blury estetic or what but its not half bad :D i recommended you for the art portal as a scouted user. you need a couple more people to do the same to get you there tho.
lineart, dont know if you did it digital or traditional, but you need smoother lines, i saw in your other piece about Hansel and gretal you used alot of line weight variation, which is good, but its still not clean and smooth line work, you need to practice doing long strong strokes with your pen if your doing traditional and fixing messed up lines if digital, paint tool sai is great for line art if your using a mouse like i do. all of my digital work was done with a mouse.
-->of course you could use shaky lines on purpose if so your doing great, if not just practice some.
digital painting, practice selecting an area with the lasso, magic wand, or whatever your program uses and use a variaty of brushes, dont be afraid to cell shade, and use harsh color changes, having everything look well gradiated and flush dosent really look that great, so you can get brushes and things to make textures and use things other than the soft brush for everything. your skin tones are great im assuming you pulled colors from something, but the hair is to soft and undefined, look up mark crilley on youtube, draw with jazza also dose great videos, they and others have videos about hair and things like that,
refrances are allways a good thing.
also backgrounds can really make your pieces like this pop, so i would suggest a brighter white background to make your character stand out more, higher contrast allways makes for a more dynamic image..
you can msg me if you have any questions want to talk about art or want to do some kind of colab or something, also you can friend me on facebook. or sub to me on youtube if you like :D
if your wandering why i typed all of this, i just wanted to help out a fellow artist and make a friend :D
