Besides the renaming of art files and better organization as mentioned in the previous post, I have been putting together pdf files of demos and art reference sheets. My latest project using bits and pieces of my artwork to create cover pages.
Here is an example of one cover in both portrait and landscape orientation.
And because I save my blog posts converting to pdf files, I've played a bit using Photoshop Elements to create covers. Some are using scans from my artwork and some are playing with brushes in the software program itself.
I still have some work to do ..... like how I want to place a title on them but these are a good start to work from.
