Move horse up to make room for long legs and over to move toward center. Then make smart object. Engage Puppet Warp and place pins for anchoring and stretching legs. Used lots of pins on hooves as didn't want the hooves stretched
Apply Camera Raw Filter to background then fade edges of horse to blend better with background. Moved ladder onto canvas- Place embed ladder cutout, downsize, flip horizontal so lighter side is on right towards sun. Rasterize it. Use perspective warp to adjust ladder perspective.
