Missing a lot things. Gerrymandering can still occur without the electoral college, tax things seems neat in theory but need to deal with corporate taxes, term limits on the supreme court would make things worse (research indicates an age out system would be better), Police system will still be fundamentally broken, companies will still continue to maximize profit to everyone but the shareholder deficit, stock buybacks are creating major issues and allow companies to game Wallstreet, are just a few things that I think are missing here that need to be addressed.
