I love how the fire lights up the buildings. Seems a bit bright though, a tad overexposed. I know you wanted the building to show. I'd still step it down a tiny bit.
oOH! A Melbournian, this is one of my favourite places. The picture almost gives you that Hot Exciting feeling of being there. We must talk after the comp :)
Your composition is good but the fire is too blown out. Maybe if you had spot metered on the fire in Av mode it might not have been so bright; this could have brought out more colour/contrast within the flames I believe.
