Good that you painted the floor olive drab instead of white, but the rest of the hull interior was white on the M10 The raised floor, the inside of the turret and the insides of the hull hatches were OD, everything else was white.
Oh, and "Wolverine" is an invented nickname by the manufacturer, not the US Army. Somehow that name has made it into mainstream books and kits over the past twenty years or so.
I'll nag about the colours again The lower hull sides were white, not OD, and the ammunition tubes that you painted OD, were black. See these pages from the TM (The floor there is white, but that's because the photos are from an early vehicle.)
I would remove the stuff on the front hull that's higher up than the spare track. All of it blocks the view out of the driver's and assistant driver's periscopes.
