It really is lovely
Comming from a manga panel too,
I always love multilayer vexeling with few outlines *____*

But some crit
Seems its a sunset it would have been nice to tint the shading with colours from the sunset.
The outlines on the red curtain and wood panels on the wall are too saturated or bright.
The outlines on the purple curtain need a tat bit more saturation and darkness to give better contrast.
The left purple curtains shading looks messy and not really like shading at all, more like random shapes. Try to do what you did with the right purple curtain, and follow the direction of the creases.

But I have to tell you, I adore the rose
Good job :3

DX I got my right and left mixed up!
I meant the purple curtain on the right looks messy and you should try to do what you did with the left one
Sorry =___=;

...Oh Break...
You are the coolest yet most-often-hit-by-tragedy guy...! wehy?!

Ehem, rants aside.
Your vector is quite well-done IMO but the colors seem a bit... strange. Um, it doesn't seem to flow well. Lack of shadows despite of the tile 'Sunset'.

That's all I can give ^ ^
