Enhance Art History Article Clarity

I have completed a draft article that walks readers through several milestones in art history, referencing pieces such as mandel-style drawings and other illustrative works. The content is solid and meant purely to inform, yet my English still carries the hallmarks of a non-native writer—awkward phrasing, uneven transitions, and the occasional grammar slip.

Your task is to smooth those rough edges so the article reads naturally for an English-speaking audience without losing my original voice or the factual detail. I need the text re-structured where necessary, sentences tightened for flow, and any ambiguous wording clarified.

Please return:
• A polished version ready for publication
• A marked-up file (Track Changes or Google Docs suggestions) showing every adjustment you make

Accuracy of art-historical references must remain intact; no additions or deletions to facts, only language refinement and readability improvements.
