Liquifying the creature
The Liquify filter is a marvellous tool for making minor repairs and shifts in surface features and details. First of all I Marquee-select a local area to work on, then open Liquify (Ctrl-Shift-X or Cmd-Shift-X). Once there, navigation and brush size shortcuts are identical to the main Photoshop viewport. I don’t try to achieve too much in a single Liquify pass, though. I find it’s much better to carry out multiple subtle passes, then use the History palette to decide how far I want to commit.
