You are amazing when it comes to drawing RID 2015 characters. You add more personality to the characters than hasbro does. Your characters are so good they deserve to be real.
Prowl is cool, I love the glasses. I know there was supposed to be a scene involving Prowl during the first episode, he would've shown up at the scene after Bee, Strongarm and Sideswipe went through the panel, he would've been Bee's superior on the police force, kind of like what you're doing with Smokescreen.
I had a lot of fun drawing this one and I really like how he turned out! I did everything possible to make his parts look like his movie namesake. He is a former Wrecker and later joined the team as weapons specializer (there's at least some Fixit in his role). His rude and violent personality makes a lot of trouble to his crew, and even worse to the Decepticons. Like I said, Smokescreen will deal with a lot of troubles.
I just watched the show and figured out how to replicate its design (or trying) on other characters. Glad you like it.
I know the smaller heads are to fit in with RID's overall aesthetic but... eh, I'm just not a fan of them personally. That said, Leadfoot looks amazing. I love how you kept in all of his regular proportions while still making him look like he could transform without any short cuts.
TF RiD is overall a mixed of Animated and Prime designs, the vehicle parts can be deformed enough to look almost different in robot mode (Animated) and contains a lot of detail (Prime). So, I had fun drawing them because I can deform parts to make them fit with the stereotypes I gave to them. Glad you like it.
