So far, so good!
AND...welcome back to it! You'll find that things have changed a lot! From the engeneering in kits to the wonderful world of aftermarket items.
One thing I see, though...ya got the color right, for the pit, but gear bays and other (non-manned) areas should be the light grey/green (RLM02) color. Early war colors were RLM02 for all interior areas...later, the pit (or manned areas) were the dark grey, like you have, but the unmanned areas kept the RLM02. Anyway...carry on and enjoy!!!
