Well the line art is okay but your shading still needs work.
The side views are still done in the wrong perspective and look flat as a result.
I would still suggest choosing a light source and shading accordingly.
You need to have much greater contrast between the different hues or shades you use. This is why some people have said it looks too black. You should try increasing the brightness difference between the various hues/shades.
