Second Paso
Personally, I like point out a bit with arrows, very slightly with my pencil, to make sure and remember pile direction.
Not everyone it does, not necessary, but helps maintain realism.

Third Paso
With the order to make sure that the silhouette remain pleasant I created a shadow unison.
Excepting the chest and paws that the've left blank.
I've remarcardo especially the lines the chest giving them a darker tone.
Now not remains very well but I do it to mark the style of shadows.
I have also added more details along the back of the wolf and his hindquarters.

Fourth Step
I have focused in working from the neck to the rabadilla and tail (I have difficulty doing so because I am lefty> _ <). I have detailed the neck compared with the hindquarters etc always working with the direction of the skin, even whether this means that I have that rotate the folio side to side. About everything must be in the same direction. Sometimes, I like doing "flowy" thought in the forms of the "V" who take the strokes that are close together, for then mix. Do not worry by small details, the hair will look better after that we focus on the rear of the wolf with a darker tone. Quinto Paso
Labour stomach part and the posterior region, the strokes must of being less crisp. I like drawing the skin a little "rough" in this area, a bit messy. You can make it look clean following the steps the neck and chest (mixture using different tonalizades). To obtain the "stacking", where hair looks a little apelmazado we combine it "W" (See step to the image ref # 4) and build from there, from the light tones and darker, more lines of chance . The easiest way of remember is that I never baso in a single line per separately, so .. If think you not have patience to do, do not complicate ^ __ ^. Once you finish'll see that not has led you more than one hours complete the textures of the skin.

Sixth Paso
This step has to do with the neatness. Using dark strokes,'ve add some lines in where I think can look good. Perhaps one shade along of tummy to give a rounded appearance. Remember! Do it with the pencil, but lose the pleasant texture that so arduously've drawn and would have been a loss of time.
