MechArm Railways and Desk Stranding combiner remix

Greetings everyone. Actually what I really wanted was a mechanical arm lighting idea. 

I really liked the look of this model

and i really liked the mobility of this model 

( https://makerworld.com/en/models/679425-mech-arm-railway-system ). 

Finally I asked myself what would happen if I changed and combined these two and this is the result. I hope you like it. I'm just starting to do this kind of design editing, so if you have any tips or ideas I'd appreciate it.
I apologize if there are typos, I used translation.
(If the model owners don't like it and want it removed, please contact me. I will gladly remove the designs)
