pixel shading practice: Mittens (BOLT)

I'm terrible when it comes to shading without using the brush (I'm not patient enough to select different nuances), so I decided I had to do an shading-exercise. I reduced an image coming from Volt , then copied it pixel by pixel, using the same colours, with the pencil. I thought it would be easier because in a way I just had to add a pixel after another ( and if I added too many pixels I could easily compare my Mittens with the "true" one). Actually, it's a long-term stuff (The black part is fine but I have mixed up the white ones TT)
phew!
I'm happy with the result but I don't know if I'll be brave enough to create an icon using this technique. XD
