@pires120013, it makes little sense to replace a 250x250 cut with a 180x180 one. 

@mons  in the game we not see the difference between a 180 and a 250. have you test the face? 

Most skins will display cuts in 250x250, so yes there will be a visible difference when a 180x cut is upscaled to fit the larger canvas. Your cut doesn't have a collar either and has some snow.

This thread contains guidelines for what we're looking for in our cuts in terms of dimensions, snow, collars, face orientation etc. and video tutorials for each element.

Can you provide us with the original source image without the background removed so that we can cut it accordingly?

If you want to give it another go yourself, I would recommend using remove.bg, which is a free online tool which removes the background to an excellent standard, for free and almost instantly.

Here's a couple of videos on how to use it, one when combined with Photoshop and another using photopea.com, which is a free online app so close to Photoshop that it has the same shortcuts, layout and icons.

If you don't have Photoshop, photopea.com is the tool I would recommend to use to tweak the draft cut produced by remove.bg. It's more powerful and versatile than GIMP and other similar tools.

this picture is not good too?

It's too small to provide an improvement, because the area taken up by the face is quite small, and increasing it to 250x250 will mean it loses a lot of sharpness.

ok no problem 🙂
