Here you go. A used a warped, transformed Quick Mask refined with a Regular Layer Mask to cover the big ugly lump. Used the Spot Healing Brush on some of the light grasses and light tree trunks in the BKGR. And then some more grass clean with the Clone Stamp (divide and conquer) and the Patch Tool. Five minutes in all, most of that for the clean-up.
Everything that I did above is covered in detail in my
Digital Basics File which includes my complete digital workflow, dozens of great Photoshop tips, details on using all of my image clean-up tools, the use of Contrast Masks, several different ways of expanding and filling in canvas, all of my time-saving Keyboard Shortcuts, Quick Masking, Layer Masking, and NIK Color Efex Pro basics, Contrast Masks, Digital Eye Doctor techniques, using Gaussian Blurs, Tim Grey Dodge and Burn, a variety of ways to make selections, how to create time-saving actions, the Surface Blur (background noise reduction) settings that I use to smooth background noise, and tons more.
