I’m thinking you’ve forgotten the most important piece of info, the price. (unless you are also maintaining online stores and other sales channels separately)

Other options to consider:
the support (canvas, board,…)
the collection or series (hopefully separate pages for each)
if you have framed the work, then framed and unframed size.

Bonus question: We don’t really have enough information to chime in on this. It is really a question of how you plan to market yourself and your work. Explore what you think your public identity should be.

For example, what three things about you are the key things that will make you memorable and help build relationships with your audience? What three things about your work are memorable and recognizably you? Perhaps focus on these six things with most of your descriptive words on your site. You can talk about other stuff, but see if you can repeat or imply these six messages in many different ways on your site without being too wordy – different words, same underlying messages. These messages don’t need to be descriptive explanations of the works. You will find the right balance of mystery and clear description to entice your audience to return. (I wish I was good at this stuff)
