Digital rendering and brushes for beginners

[darktiste]

Your shadow side should have softer edge you can use the blur tool to do that i think if am not wrong.Also your form underside should be much dark where it hit the flat surface.The cast shadow also play a role in how much bounce light you get and the surrounding area color as play a role in how much light is reflected around but that also depend on the light source intensity.Those are thing you should practice.How does one practice observation?By taking note but of course you need the theory to understand what affecting your object.Observation is exactly that describing to yourself what your seeing and why this thing look the way it does.

For a final note always indicate where your light source come by indicating the direction and the distance of the light source(if you know where it when doing drawing from life)or estimate the intensity of the light source to help us give you a better inform critic.
