I am Leonardo Pereznieto and today we are going to draw some marbles.

We start by drawing a circle with a glass, of course

you may also use any other round object or a compass.

Then with a white pastel, let´s do the brightest lights.

In this case I use the blue pencil to sketch the

ink blotches which are inside the marble.

With the same one or with a pencil you may do the

small bubbles which I trapped in the glass,

and with the pastel do the reflections on each one.

Having done that

we are ready for the colors!

With the gray we shade the area that is on the upper right.

As I told you on the water drop tutorial, the beams of light go through a

transparent object and illuminate the opposite side, leaving a small

reflection where they originally touch the surface.

Maybe I am talking too much and I didn´t even tell you

how to get in the colors, but that´s easy...

fill it in, and then with some different tone, draw

some texture or shadow lines. In regards to the water drop video

I´ll give you the link at the end of this one,

so you an watch it.

Let´s use a brighter green for the area on the bottom left

and with white, we lighten a bit.

We should also do the reflections of the ink colors.

Very well! I love drawing!

By the way the complete list of materials is in the information bellow the video.

Depending on where the light source is, there may be a bright reflection in the middle

of the shadow.

With the gray and with the white, we achieve this effect.

You may layer in, one on the other one, to create

a soft change of tone.

Excellent! I like how it is looking.

We may simulate some scratches on the marble.

Let´s reinforce the shading of the bubbles and if you

can give me 60 more seconds of your valuable time,

I would like to show you one more thing...

let´s do a second marble, but as this is going to be a little

bit further away, I want it to look a little bit out of focus

so as to give a depth effect, therefore in this case

we are not going to draw any sharp lines but

rather they are going to blurred both inside on the border

of the marble, the colors in the middle are also going

to be blurred.

I would love it if in the comments you could tell me, what do you

think about this technique.

Thanks!

Here is the result...
