Those thumbs aren't only sharped, there are some other filter involved. Look at the smooth skin for example, no way you'll get a similar result with the unsharp mask only.
If you're in need of someone who's able to produce exactly the same quality or better, talk to Alessandro 132-818-937 and tell him Thomas sent you.
