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: Unity: Animated texture from image sequence - Part 2 | 41 Post
and it working perfect for it’s own images.

The Print Screen of my problem is blow [1]

Check the “Max Size” parameter of your sprite (here 1024), if your image has a greater resolution up this one.
