Wow, you mused the life of a duck. x] Yup, I used a ref, but this is one of my first Pixels, I thought I could use a reference to create it. Btw I'll try to make it better. Thanks. ;)

Nice, but you are obviously constrained by using one ref only.

What you should be doing instead is find lots of refs, sketch them all quickly on paper. At some point you will start understanding the basic shapes of a duck, and you can draw your own duck in the angle and pose you want.

Hmm, I'll try to fix it, maybe changing the lightsource. Thanks ;]

 Distorted foot, tail shouldn't be that bright, shade on head could be more round.

  Hmm .. nice work, but the line art is blurry in some places. The dithering in his belly was a little too weird.

See yaa o/
