Hallo Fromper,
indeed this position is totally won.Well there is nothing black can do here.In such positions it is very important not to rush to much,black cannot do anything here,so it is the right time to develop all your peaces ,then it will be very easy to win it. E.g. Bc4,then you castle short and double your rooks on the d-file (Rd6&Rfd1),then blacks position will collapse!
