omg im so sorry i forgot to comment on this! i thought i did
anyway, here goes :
The different layers of colours and smudges on the tree and ground help define the depth and distance of the objects.
the sky is just amazing (love the cloud on the left ^^)
the border is simple, so it doesnt distract nor detract from the artwork, AND its elegant. what brush did you use for it?
The combination of vector and traditional style is class. I really like your colour schemes as well, very light on the eyes. If theres one thing that I find unusual in this piece would be the black figure, in that I can't determine what it is? haha. You got a very freestyle handiwork, through observing the frames. A very succesful piece in many aspects, congrats.
*cries* oh god.... I actually forgot art could be happy until I saw this piece... no, I really mean it. I've been so depressed lately and just... *continues crying* thank you. Thank you so much.
...gah! I'm sorry, I must sound really weird, but... anyway. It's a great piece.
