Good work but i think the castle is to 2 dimensional to really fit in with the landscape. The sky looks great but your shadowing is a little off. I would angle it maybe five degrees to the right and stretch it out more, its a little too close to the castle for the setting sun. Also maybe a little more blur the further the shadow gets away. And you should be able to see a little of the inside walls of the outer pillars, but other than that great work. And to fill up the last few words to send this, a slight yellow hue on the highlights over the ground wont hurt anything.
First thing that comes to my mind : SO COOL I WANNA GO THERE MOMMY. MOMMY!! I WANNA VISIT WONDERLAND. But since its a picture ill settle with dreams xD
Your work is great. I feel calm and excited for winter. Which is funny because I dislike winter, its cold and after a beautiful snow fall, the cars ruin it with pollution. I love the bears! So cute and works great. The light from the sunrise in the window (I think) Looks welcomeing. If I to close my eyes, Id see a grand entry way with Pearl like shandalers and stairs high as the sky. Now If do not mind, I am in the mood for Hot chocolate. Have a nice day and a Pleasent Winter.
