Your missing a 5 yards, so your field is 95 if I'm right.
And yeah, the lines are to short, the field is abit to short and not wide enough;
Coincodentially I just got back from a game I played, which we won 14 to 6. So I should know how a field works, Lol. So for a school field, its nice, but needs more lines, brackets and such. Nice work though.
