Artblock Paradox

Hey there! Regarding your artwork, here's several problems.

First and most noticeable error is that the pages on top of the bed and below it seem to be located on two differently angled planes towards the viewer. This is because their vanishing points do not match - the left and right sides of the pages on the ground below the bed seem to converge around the center of chest area of the person on bed, while the pages on top of the bed seem to have a vanishing point far out above where the drawing ends. This makes the entire picture look off, even if it's hard to tell just what is awkward at first glance.

Second, the person on the bed hardly has any dimensions in relation to objects around it, only the hands have hair flowing around them in 3D. You can't distinguish where the sides of the body are, thus it's hard to tell where the papers on top of the person and next to it begin and end - there is no 3D alignment or shadows indicating what's where in this area. The left arm is positioned more like it was rested against a table if you flipped the image upside down face instead of how it would look at this angle - with thumb and thumb's side of the palm being most of the area you see, other fingers being covered or having only the top of the furthermost fingers visible.

The head also seems to lose a dimension. As it is right now, the left arm on the forehead seems to be facing flat against the bed's level, which then requires the face and head be absolutely 2D. The center of the head should be more prominent, rounder and have each hair strand be visibly traceable from the scalp in a 3D way, instead of hair locks being stuck to an invisible starting point behind the face; also, the head should be higher above bed, and tilted in a way that face isn't facing the viewer so straight.

To get the right angle for the head, it should be drawn within a 3D cube modelled against the same vanishing point that all pages - below and on top of the bed - would converge in, with the cube's bottom square matching the level of top of the bed.

I hope that any of this helps!
