i think you could of found a better picture of Gir. also did you save it as a gif or something? i have crapy eyes but it looks like you did!
oh, png... it looks like i gif...
So imho:
- i think the black is a bit to dark? makes for a very strong contrast.
- google images! Gir! less pixilisation! unless that was the point, in which case you should of gone more extreme to make the point obvious.
- also i'm not a fan of the text, which im guessing is Arial. mainly becuase i feel artsy farty and i like exotic / interesting fonts that people don't see all over the place!
i like the idea though

Also a note; since you ar 16 i'm guessing you are an up and coming budding Graphic Designer?! Cool

i suggest visual communication and design as a VCE subject if you ahvnt already chosen.
PS, pm me if you wanna talk about yer website
