Hey, shown here are item sets and standalone items selected from over 300 cosmetics and weapons created and sent throughout the years, hoping to be accepted into use within Team Fortress 2(and a bunch did!).
The Team Fortress 2 Workshop and its community has taught me a lot about analayzing,matching(and sometimes refreshing) art styles, working under strict polygon and texture size limits, as well as strict deadlines which I had to enforce on myself, inventing interesting compositions for promotional art and working with a team or closely with a Concept artist[and surprisingly even some 2d animation!].
Most of these items were done within 1-3 days each, promotional art included.
