I built these a while ago, along with my previously posted LEGO G1 Optimus Prime.

Optimus Prime:
This is the one that started it all. I was bored one day and decided to try to make a transforming Optimus Prime from the Live-Action Films out of LEGO. He does partsform more than Blackout or G1 Prime, but he's easily one of the more accurate (except for his backpack).  

He even has some accurate weapons (which are on the floor behind him in that last picture):
Energon swords:
Stored on his arms:

Activated:

Ion Blaster:

And, as previously mentioned, he transforms:









And vehicle mode:

Blackout:
At one time I had built a Voyager-size, one piece, transforming Movieverse Blackout, but sadly he got destroyed. I built this one so Optimus would have somebody to do battle with.  

His weapons can be seen in that image, they're small, one-barreled guns on his wrists. I used to have his tail rotor become a buzz saw, but sadly it went missing when I took the pictures of him. I also didn't have enough pieces to finish his main rotor.  
Transformation:




Vehicle mode:

Autobots, roll out!

 

Good as a moc'er myself i like your creativity
but if i might give advise the bigger the easyer to work with

 

pretty good

 

Thanks! Yeah, building bigger models are much easier to work with, but I didn't have many pieces to work with, so I made mini models!  

Thanks!
