needs work...
The "g" chord is incorrect, and should be moved up a fret and the placement of the tabs reversed (it spans the same two frets as the "d" chord). I recommend that you fix this game up, using some people's not-so-nice comments below as guidance. It's not a bad try at a tutorial, but I believe the process of revising this flash will help you learn.
according to your strange placement of the guitar, which is upside-down in my opinion, the "G" chord should look like this:
X0XX
0XXX
XXXX with this side being the rightmost end of the guitar neck
XXXX
XXXX
X0XX
