Welcome to Librarium Online!
I've finially finished my modular carnifex. The heads, carapace and limbs are all attached with earth magnets. Works great for quick switchouts. Plus I don't have to buy more carnifexes to fill out different roles. Need two sniperfexes? done. Two dakafexes, easy as pie!

I just finished building me one of those. Takes a lot of extra time but it's fun switching out the options, plus saves money in the long run.

My next will be one of these.
I have the magnets, Just need a new carnifex to work with since I got the magnets after I got my first carnifex.
That is a well made Carnifex and it isn't easy to see that magnets have been used which is very good. I can see the attraction of using magnets on Carnifexes though I wouldn't because I'll picky and set in my ways. I think the paint job you have done is also very good and above the average. I like some of the details on the weapons the most, I think your attention to these areas is well worth it.
I decided awhile back to make my two carnies modular with magnets as well, but I didn't think of converting venom cannons and barbed stranglers to take up one side. Nuts... now I have to go buy weapon sprues...
