Hello my friends and welcome to another Tuesday of Tutorial!
I am Leonardo Pereznieto, and today I will draw a Gecko.
I will use this Tutto3 Mechanical Pencil and I will try to loosely sketch the shape of
the head, which is sort of triangular.
Then, on this general shape, we can begin adding some of the detail, such as the orbits
for the eyes, which stick up like this, and then, down here the nostrils.
Alright.
I make some parallel guidelines to go straight.
And I correct the position of the eye.
They have long, reptilian pupils [laughs].
On this part below, they have soft, loose skin.
Let´s draw an arm over here and his body.
His hand with his toes and his shadow.
I´m sorry, I will erase this eye entirely because it was too close to the other one.
Let´s measure, I´ll make it more far appart.
As it should be.
And a little lower.
I had erased my guidelines.
Ok, I think this is correct now.
I trim the line slightly with a thin eraser, by the way, the list of materials is in the
information below the video.
A lot of people have been asking me about the Tutto 3 Mechanical Pencil, which is now
available again on Amazon.
Geckos are a type of lizard, and they comprise about 1500 different species, all in warm
weather.
Most of them are nocturnal.
I switch to a larger and softer lead for the darker tones.
Their eyes have adapted for an excellent night vision and they are 350 x more sensitive than
human eyes, in regards to color perception.
So practically they distinguish colors in the dark as we do with light.
And talking about color perception, I filled my pencil with a blue lead, because I want
to deliver this effect of the blue eyes on the otherwise black and white drawing.
As you saw, I first did the shading in black and white, but then I changed my mind and
erased most of that shading and redid it with blue.
Their skin has something similar to large scales which have been observed to have an
anti-bacterial property killing germs and bacteria in contact to the skin.
Most gecko types have no eyelids, but they have long tongs and they leak their eyes to
clean them from dirt! [laughs]
They´re pretty funny when they do that.
About 60% of the gecko types have adhesive toes, which allow them to climb vertical smooth
surfaces, easily.
A recent study has shown that gecko adhesion is mainly determined by electrostatic interaction
caused by contact electrification, so as they walk they produce like mini-magnets.
And these amazing feet are also self-cleaning and will usually remove any clogging dirt
within a few steps.
The surfaces that don´t transmit electricity, such as Teflon are much harder for the gecko
to climb.
I´m drawing the cast shadow and then we can choose to smooth it with a stump, with a blender.
I will also smooth out and blend some of the skin.
This also gives a tone and can be used for shading.
After blending, we reinforce some of the darkest shades, and then with an eraser, we can pull
some lights.
We give it the last touches, the last details, and it´s ready!
