So finally, here's my own design!

I really love the horns, but the antennas can be exploited for emotional responses, but I made them spiky like his previous horns.
Actually, in the fic, he explains that he used to have a pair of horns, however, upon arriving to Earth, one got damaged due to the landing, and a few years later the other broke. So he made himself a pair of antennas since he didn't remember exactly how the horns looked and one human that was his driver for a while called him Bumblebee due to a buzzing sound his motor made.
Here's the full version:

I'm still designing his full body, so that one will take a time for now. I'll be releasing more human characters (two to be exact) before his full design. Also here's the link of the fic if you want to read it!
I'm finally free! Now onwards designing Prowl's face! (No, I won't do a choose your Prowl image)
