You also messed up parts of the right side (market).
just check the hight of some Pixels there compared with the other side.
I hope you ment 5 minutes, 5 houres seem to be a bit... dunno.
Well its kind of ok, if it was your first try, but still 5 hours its pretty long for something like this.
I just used 2 riped sprites and put them togeather, like i think you tried, took about 6 minutes. sorry if the ripped sprites got errors in them, did not check it.
However, the 16*16 order should be right and it may be used within a tileset.
Edit: Is it possible that there is a rule, witch makes it impossible to pose pics using img-tag until xx posts, like the "no links under 15 posts"-rule?
