No Sales Despite 100+ Assets – Need Feedback

I could be wrong, but I think you may have been swayed by YouTube videos promising a steady flow of cash by creating and submitting AI assets. It doesn't work that way. In any case, 100+ assets (especially these, taking critiques into account) will not result in sales. Work on getting 1000+ QUALITY assets submitted and you might start getting an occasional sale. Inspect your work at 100-200%, correct any issues, and work on unique content.

Do what Jill _C says regarding key words. Your immediate goal should be uploading the next 50 images, and make it a goal to do so in no more than two weeks, which is more than enough time. Above anything, have fun at it, and remember this is a long term play.

In the grand scheme of things, 100 assets won't generate much steady side income. 

For that to happen, you'll need a portfolio of 6,000 or more assets covering a wide range of subjects that are in demand.

Obviously, this won't happen immediately. It takes time to build a content-rich Portfolio.

Acceptance doesn't guarantee sales.  

Everything depends on customers wanting & finding what you're selling.

Can you post a link to your Profile Page?

Search in the Buyer portal at stock.adobe.com using the top keywords on a few of your images. This will allow you to see what you're competing with. With more than three-quarters of a BILLION assets in the database, there is plenty of competition for virtually every subject. If searching for your images using your keywords results in thousands of results, and yours don't appear in the first few pages, they're unlikely to ever be seen or licensed by Buyers. Make sure your titles and keywords are as accurate, thorough and descriptive as possible.
