@nuttawut048, not a bad cut, but there's still a fair bit of snow around the head. Can you watch this video to see how you can spot it and easily remove it in the future?

Also, with a source like this, a 250x250 cut would have been possible. I'm not sure you're aware, but in the last year or so, whenever a source is large enough to allow it, we've given the possibility for cutters to produce it in 250x250 instead of 180x180 to retain a higher quality. This is because (a) some skins display cuts in 250x250 (and 180x180 cuts don't look so good when upscaled) and (b) SI are also producing their own cuts in 250x250.

Please keep this in mind for future cuts

What program and what technique are you using to cut, out of interest?
