3D Drawing; A Bird

Hello Hivians,
Today I did a 3D drawing of a bird standing on a paper. The drawing is made on a plain white card board with colour pencils and HB pencil.
It appears that the bird just landed and needs to take observation of its environment.
3D sketching is a type of sketching that produces realism. With the creative effect of the artist 3d is produced on the same surface like other art but differently drawn, differently adjusted, differently snapped and differently seen.
In the picture, it appears that the bird is standing on the table and not just ordinarily drawn. That is the effect of 3D.

Thank You!
