Week 3 - Still Life - Composition

These are the four compositions I came up with using these five objects. I'll refer to them as 1, 2, 3 and 4 counting left to right, top to bottom.
N1 has some very strong vertical lines which seem to interfere with the almost horizontal lines of the tube on the right. There are no clearly defined implied lines. The negative space line is very angular, resulting in an intense and rough feeling. All of these issues make the composition slightly disturbing and rough. Objects also seem to be focused on the right side, which puts the composition out of balance. All of these flaws make the composition unpleasant.
N2 has some really nice implied lines that are marked on the drawing itself. Again, the line separating the negative space is very complex making for an intense feeling. The two implied lines don't seem to be enough to soften the look and guide the eye. The cup on the right and the tube behind it are positioned very nicely, as they don't obscure each other, but they don't "kiss" either. The cup on the left, however, is at a very bad position - having it so close to the book and parallel to it, confuses the viewer even with the slight overlapping apparent. The pyramid is also at a bad position, being far away from the other objects, making it seem like an orphan object.
N3 appears to be the best composition amongst the four on the image. It's got an interesting, yet calm negative space line. There is also a very subtle implied line formed by the top edges of the two cups and the tube. Having three of the objects facing a similar direction also helps soften the scene, because it gives a more natural feel to the setting. The pyramid's top edge is almost kissing with the book's edge behind it, but again the fact that the objects are laying on their sides seems to give enough reason for the pyramid's position. Even without an image frame, there is a rule-of-thirds focal point forming at the top of the pyramid. There is an obvious mistake in the form of the leftmost cup, but this is not a composition issue.
N4 attempts to create an interesting composition by setting the objects in a very unexpected way. However, having the book support one of its corners on the pyramid makes it bend, which in turn appears as a mistake in perspective without the shading to reinforce the bended feel. The cup on the left seems to be positioned well, as it is not kissing any objects, nor it is left too far from them. The tube is showing an edge under the bended book which is confusing to the eye. In overall, this composition seems unpleasant, because the objects are situated in a way, very unusual to real life.
