@Zainus Shaleh R, not bad but a lot of images in this pack contain snow. Here's how to easily spot and remove it:

Also, all images must have a collar within 2-3 pixels of the chin.

In cases like these images where the collar is probably a bit lower, this is the technique to use to nudge it upwards:

Finally, in cases where the head in the source image is tilted to one side, it is recommended that you rotate it before cropping it:

I'll fix these ones myself, but please keep all the above in mind when making future cuts 👍
