The contrast between detailed/fully-realized (the character, raven) & the superflat simplification (background, grass) make for a stylized yet soulful piece utilizing two different types of art-style to create a wholesome picture. Especially the character's design and personality elements are lovely fusion of fantastic & realistic; old world (magical elfin feel, raven imagery) yet modern (her inner bra straps (good job with making it important article of clothing instead of tacky reveal), bun hairstyle, Alt. piercings).
And extra praise for realizing respective anatomy of both her & raven, the bird is accurate to real life giving this art authenticity while the girl's physique is elegantly fit, especially her curving pose and smooth yet firm wholesome upper arms. ☆
Lastly choice of colour schemes really brings out that small point between warmth of sun and coldness when darkness falls, bright yet still balanced to give it a deep encompassing hue. Her broom's glowing energy hints at special ominous powers that she could harness or is in control of.
Thanks So Much for this, hope you could follow up with more drawings of her or usage of such warm evening atmosphere.
