The texture of the buildings is amazingly done. I especially love the shadows on the eaves and the reflections in the windows, they add a whole new level of realism to the picture. That the colors of the buildings grow lighter as they appear farther away from the viewpoint adds so much depth as well. This plus the beautifully blended colors of the sky, just make the drawing seem real, even though its clearly not a photograph. I don't pretend to be an art critic, but all the same, this is flawless. By contrast, Kiki's colors are much stronger than the background, its easy to see that she was added later. It gives a feeling that Kiki is farther 'forward' than the buildings, rather than higher up in the sky like the birds. Not a bad thing, it makes her noticeable, and she is the focus after all. But its a break in the artfully blended light scheme you have going, almost like she's a stamp (though wonderfully drawn all the same). I think she could be blended into the sky better. Though, Whether you like the way that Kiki pops out of the picture or not is more personal preference than anything, and its the only thing I can say about this picture that isn't downright amazing. Did I mention that I love the black cat sitting on the chimney? Let me end this by saying that this work is much better than anything I could draw, but you asked for a critique, so this is my honest opinion. Probably one of the best drawings I've ever seen. Period. Hell I made an account just to review this drawing.
Love how you did the houses The bricks and windows and gutters and whatever. The smoke is also very cool. And the colors are fantastic, they give a great vivid feeling. Did you use water doing the clouds?
This one and your Princess Mononoke works are all my favourites you really do manage to capture the films in a way that is unique to your work... I hope that made sense I find it hard to describe in words but basically I LOVE this!!!
This looks so beautiful! I love the way you drew everything, the shading is just perfect, the way you colored it is absolutely gorgeous not to mention the colors that you actually used (which were perfect as well!). Everything is just amazing, especially the sky and Kiki. You made her look so pretty! Fantastic work! Really! I think you outdid yourself.
