Hey Gordon
A nice kit this one, and with some patience and research can be made quite accurate to the real tank it portrays.
You seem to have made a good start here though.
If I may add also that you should keep retaking the pics until you get some clear in focus shots? Easy enough to do in a digital age, and helps us in helping you

I will suggest having a look at some of the Concord series of Shermans at war. There are numerous photos showing this and similar tanks and how the stowage was maintained and even close ups of mud accumulation and spatter etc. Good to use as reference...
