I recently discovered the work of Polina Yakovleva an illustrator based in Moscow, Russia. Her illustrations have both soft hues and deep dark colors that give off a really lovely dreamlike feel. There is a lot of detail in every piece, one could spend hours looking and finding new elements every moment. For example: the second image, which is my favorite, the owl is sitting under a quilt enjoying the company of its friends who are bust doing other activities. The whimsical and serene ambience in the scene seemed to come straight from a children's book.
Polina's more wonderful work can be viewed on DeviantArt where she has a profile by the name of SmokePaint.
