Animation (Images) getting blurred

I am new in Unity2d creating animation via series of images of the player... and images are very clear... but when i add them in my animation they are getting blurred.

I am following this tutorial: http://www.41post.com/4742/programming/unity-animated-texture-from-image-sequence-part-2 and it working perfect for it's own images.

The Print Screen of my problem is blow [1]
