Nae bad
Well, I think that a Scottish theme marching tune would have more of a snare to it - this is a drum kit snare, as opposed to the sharp, crisp sound that you get with a marching band. Have a look on YouTube for Trooping the Colour and you'll hear exactly what I mean.
Still, the sound in the background hardly reflects bagpipes either - I think that you're making close approximations there, but it's not quite what people are after in a proper Scottish tune. Given that you've taken main inspiration from the computer game Worms, it's got a ways to come just yet :P I can hear the first few bars "We are worms, we're the best and we've come to win the war", but then it does change. Perhaps change it before then, so that it is only inspired, rather than copied - you'll get far much more credit.
