The composition is pretty strong and it is interesting in subject matter and form, however there are some inconsistencies that really bother me and, I think, take away from the image.

Pardon me as I lack architectural vocabulary and fumble through this. The thing that sticks out most is the archway tower at the top of the stairs and it illustrates what is going on in the rest of the piece. You have this amazing and detailed linework with all those bricks and other things that creates this wonderful sense of depth and form, but you get to the roof and it diminishes. You get to the crownpiece and it becomes disturbingly flat. It's almost like two different artists did it. One had the charge of creating the walls and arches, and the other did the roof up. It lacks depth and it feels like you just forgot about it. There isn't even adequate shading through color to block out the form.

The eye is drawn to detail and contrast. The two sections that the viewer wants to focus on are the archways and the feathers on the ghost's head. The ghost, however, is a much more effective figure than the tower. The more gradual change from defined to suggestions of form works well. The form is built up not only of line, but also with the shading and it is quite beautiful to look at.

A solution might be to either tone down the inkwork in that archway (as much as I'd hate to see it done as it is beautiful) or bring up the rest of it to that level (from there forward, the background is fine as it is and should be less defined being back in space) either through the linework or through brushwork.

It is a good piece, but it just doesn't look finished at this point, which is highly distracting.

I thoroughly enjoy this image. The composition is very nice with the illusion of depth (fore ground, middle and background). I'm captured by your use of perspective with the plane angled rather then the vanishing point right in the middle. Your consistency is beautiful.

I only have couple problems with it. The building in the middle ground. I feel the intensity of the black detracts from the figure on the side. I know I should look at her, but my eye is heavily attracted to the building. She is also a bit cut off and that also messes me up because the space she is in feels cramp. She is stuck in a corner and no way out. Almost claustrophobic.

Other then that, I feel you're golden :3
