Nicely done on the figure John, especially as it's your first attempt. One very minor suggestion though - see if you can reduce the sheen on the trousers a bit. If a matt coat leaves a slight 'frosting' effect, that's an advantage, as it simulates the texture of the cloth nicely.
I've seen some really excellent figures in dioramas, that have been partly spoiled by the sheen on the clothing, but yours looks the biz overall.
Coincidentally, Wubke is the subject for one of my Bf109E builds for my BoB collection.
