Hey Pabu cute; I'm a bit late, but nevertheless, welcome to Avatar Wiki. Great job with the edits you've made so far, it's the little details that are the basis for a high quality article. Keep it up. :)
Heya, welcome to the wiki! I uh; I'm sorry to come bearing this news but I deleted the pencil drawing you uploaded of Mako. Per our Project:User page policy and our image policy we don't keep images on our wiki unless they are hosted on one of our articles.
The user page policy does say you can hotlink up to three images though. So just upload the image to photobucket, then put the direct link to the image in your page and it'll show up. :)
