Sounds way out of my skill/patience level! My Mac lags quite a bit. Not sure if it's the age or the Magic Mouse. Maybe I'd get better results with a Wacom? Or I just need to update my machine.You did well, there's a nice dark background and good separation of the subject from it! It's a majestic bird!
Keep in mind Peter's suggestion in the other thread of using the masking when applying your sharpening, if you don't already. You can also selectively sharpen areas too through the use of the brush tool, further refining its application through luminosity or colour selection refinements once you have brushed it on.
