It seems to be coming on well Serenity, there's a couple of things you might want to look at though.
First, you can keep the serial numbers on the inside of the vertical tail. The number on the left inside vertical tail panel on the file needs to be mirrored, with the RH panel left as it is.
Next, most of the panel lines on a skin represent the edges of panels that were rivetted together. The rest are things like the edges of control surfaces, hatches and doors. These sort of lines represent gaps of anything up to half an inch in some cases and on a real aircraft you can see this sort of line a lot further away than you can see the panel edges. Now on your skin all the panel lines are the same opacity. Things like the hinge lines are not anywhere near as visible as they should be IMO.
The easiest way to get round this is to make a copy of your panel line layer, call it something like "heavy panel lines". Change the colour of the lines on the copied layer to a bright colour to make them easier to edit. Then simply erase all the lines you don't want on the heavy layer. You should be left with the hinge lines of the flaps, rudders, elevators and ailerons, the bomb bay and undercarriage doors, and the engine cowling air exit flaps. Once you are happy with the editing turn these lines back to black and adjust the opacity of the layer. You want the weight of the lines to match what you would see on a photo of a real B-24 viewed at the same distance.
