i can't say this was even mildly humorous. not to put you down or anything, but it just had no...character. a narrative of bush being abducted by aliens with no jokes/parody/anything just isn't what unnews is aboout. i recommend going to the featured articles page and reading some featured UnNewses if you'd like to improve this article. your two points were for the 'not from mexico' intro, which is good in concept, but needs better delivery.
i will say that this is a good find; UFOs being spotted near the presidential ranch seems ripe for some kind of parody. however, bush has been in office for eight years now, and the subject is so...tired. focus more on the aliens.
no images. you don't need to find a non-copyrighted image, we really don't care about that stuff here. take a look at any of the other articles on bush and borrow a picture from there. a simple picture with a witty caption works just as well as a detailed picture.
this one needs a lot of work. throw two images on there (the accepted number for an unnews story), one of bush and one of aliens. rewrite that mexican alien joke in the beginning, and try to develop the rest of the article in that vein.
