Vast improvement IMO, the new colour scheme really helps. You've got some weird detail on your normal though - those channel and indents on the frame seem a bit arbitrary - like they're just there for the sake of being there on the normal map (especially that weird squiggle). Don't think it needs it TBH. If you want something there then consider maybe making something that looks like a small access/fusebox panel or something.
Image below points out the area I mean.
Can't wait to see where you go with the texture this time. The new colour scheme is a far better base to start from.
