To expedite the creation process...
...I've begun to label layers in Photoshop as I create them with clear/consistent descriptors. This might be a "no-brainer" for professional digital artists, but I never labeled them before. The numbers were enough before.

But hey - it works. I usually end up with LESS layers as a result (smaller PSD file sizes) and honestly it does speed up the process.

Art creation certainly doesn't HAVE to be swift. I hate rushing. But more efficiency is more efficient.
