Sources should be put into the image upload page itself. It's not a good idea to download and then upload from file if you can avoid it. See help:upload for more.
Also, you should aim for significantly more tags on upload. 20 is the suggested amount and it'd be pretty easy to get there on an image like this. See howto:tag.
Lastly, you've tagged a completely different artist than the one who actually drew this. Please be more careful in the future.
