I see at least five good city sites.
2 W 2 SW of Berlin- drop a city in that space and you have immediate access to 2 shielded-grasslands. In addition, it'll make it easier for you to later bring irrigation from the rivers down into the desert-plains area.
5 SE of Berlin- access to at least the oasis (2F, 1S); worse comes to worse and it's a worker factory.
3 NE, 1 N of Berlin- drop a city on the flood plain and eventually you get access to 2 Forest w/Game for a very productive city.
6 N, 2 NW of Berlin- at the river start, drop a city for access to the fruit and the iron- lots of food and lots of production.
3 N, 2 NW of Berlin- drop a city there for access to the food and start a worker factory for further clearing.
And I can't even see what you have to the south- plains can be fine if they can be irrigated, and cows in plains are super.
Consider also- you have access to iron, and extending into the plains in the south and the hills in the north means you're likely to find horses. The desert and mountains are a good bet for saltpeter, and with all of that jungle/marsh/desert, you will be sitting on top of major oil and rubber supplies (marsh providing oil in C3C).
A fine starting place. It may be a slow builder start, but look at it this way- the computer is no good at slow builder starts, and his encroaching cities will have to be in jungle or plains... which means that by the time you're ready to do some land grabs, your enemies will have dinky undefendable cities lining your border.
