+++++++++++++++++++++++++++++++++++++++++++++++++++++++

Shes very modern looking, and has gracefull lines. I like the three funnel layout.

She has clean lines yet she gives a sense of underlying power. A broadside of 5 guns is quite impressive. Speed is good and armour very good for a cruiser.

Revised the picture some...that's all.

Although the new Dutch and Danish players may be interested at seeing one of the neighbour's toys...

Nice toy!
