RE: Eye realism, step by step

Good friend here I leave you a few simple steps of how you use the pencils watercolor.

you have to check your design with Color Pencil, water-soluble (dry-cleaning) (I recommend that you use a pencil to mark).

Covering large areas with dry pencil and sliding the brush wet with water, the watercolor effect is achieved.

With the brush wet with water, slide it over the tip of the pencil's Color watercolor, is achieved "load" the brush with colour, proceeding to paint directly on the surface.

Here I leave you two easy techniques:

Sanding:

with a fine-grit sandpaper, rubbing the tip of the colored pencil water-soluble "sprinkled" in the areas where you want to colorize. Then slide the wet brush and dissolve the sanded particles.

Joint sanding:

following the procedure above, with the difference that you can use two or more colors with an infinite number of colors.
