MasterModels by Apoloniusz Musialek. He is a Polish model builder living in London, UK. He has recently won the AK Interactive weathering competition on Facebook and have really inspired me over the last year.
This Opel Olympia diorama is set in 1/35th scale and is called "Shallow Crossing" and once again I really love the way he used the water effect. This is not the model he entered in the AK contest though but I'm sure it can be found on his blog.
