Yea that is a fine place for it, also you might want to set up a script that detects the location of there ip and assigns them the proper language based off it.
what about a Drop Down Menu that says “Choose Language” then users can select it if it’s there. i think you can do without the “Downloads” text your icons are intuitive enough, or you could find/create even more intuitive ones. (www.istock.com, has some great iconic illustrations) - removing the downloads text would give you plenty of room for a drop down.
