Excellent paint job! It looks like you made a few improvements as well like the end caps on the wings
The Revell Slave-1 kit is a surprisingly nice kit. It is a little smaller than the Fine Molds 1/72 kit (which supposedly is oversized for 1/27 IIRC?). The pilot figure of Fett is very close to 1/72, maybe more in the 1/74 to 1/76 range? I don't have the AMT kit to compare it too, but I understand it is pretty close in size to the AMT kit.
I've got some photos documenting the size difference between it and the Fine Molds.

In most places detail is exactly the same except for difference like certain assemblies being molded in one piece and having "filler" to get rid of undercuts where the Fine Molds one would have separate pieces. Most of that is easily fixed as I have been doing.
