I too, think you are being too hard on yourself Easy! But I have to agree with you on the help of the camera to see things you cant see yourself. Thats the great thing with the digital cameras, is that you can photos after each stage and critic your own work!
Question: Are the Tamiya walls, detailed on both sides? I bought some Italeri church walls and had to use plastic card to square off the backs. Just wondering as I was thinking of buying these for some handy little fill-ins.
I love the mud you have used on the sherman. What did you use? From your photos it is easy to see that there is no mud behind the boogies. This stands out a bit. maybe something else to touch up !
