The results are okay, but I've forgotten almost everything I once knew. But hey, that's one of the compromises for switching mediums and project-types as frequently as I do. At least I remembered where the commands were. The atrophy showed up in more in my creative judgement - just couldn't get the images to do what I wanted.
After a frustrating first half-hour, some of the skills started to show up and I could at least begin to tee some of my ideas take shape. Like I said, the result is so-so, but it really felt good just to play around and stretch my Photoshop muscles again after so long. The experience reminded me of why I used to like working in this medium, so there might be more projects like this in the future.
