Dasmoto's Arts & Crafts Semantic Feedback

Just completed the Dasmoto’s project and wanted feedback. My site looks exactly like the desired outcome I was just wondering how clean my HTML and CSS code looks. Also, I know its probably not that important how I ID the images, so using "first ", “second”, and “third” wont cause any SEO problems right?

Your coding looks great! As a beginner I can clearly read and follow it.
The only thing I would say about the id’s is if this project was larger would you be able to easily identify what and where they were? Or, would someone else be able to?

Thanks! defintely, might want to change that.
