Hi Jessica! First off, really beautiful pieces.
What I've discovered is think of your information like a pyramid. Most concise on top - most detailed on bottom. The top would be your measurements and other information about your piece, the facts and maybe a couple keywords to keep it from being monotone & to optimize it in searches. Then move towards the who, what, when, where, & why's of your piece. I like that you talk about your process but try to consolidate your information. You want to invite people in slowly.
Also, short, punchy sentences. Separate paragraphs every couple of sentences. Big bulky paragraphs are usually a deterrant. I know I won't read listings that seem too long or detailed.
Hope this helps!!
