If this is your first try, then it's not too bad, but there are some problems with it. Bdejean is completely right, but I have a link you might find helpful.

This shows strategies which can work for 100 flags. I've managed to last for 85 flags using the best strategy there, but apparently it can work for up to and over 100 flags with a bit of luck.

There are also even better strategies which can last for thousands of flags, like this. It doesn't look strong enough to last, but this shows how it works.
