Dmitry Treukhov contributed to the EaW-Team/equestria_dev repository by delivering three visual asset updates over two months, focusing on asset management and art consistency. He replaced character and advisor portrait assets, such as Strongheart and Flim & Flam, ensuring visual improvements without altering gameplay logic or underlying systems. Using Git for version control, Dmitry maintained clear commit histories and traceability for each change. His work involved updating asset references, refreshing advisor icons, and removing obsolete files to streamline the asset pipeline. The updates, implemented with GFX identifier management and image editing tools, enhanced visual polish while minimizing risk to game stability.
