Honestly? I love to draw pretty much all of them!

I will say upfront, I am not very experience in drawing the BW era characters, I have done a few pics of some, but overall not alot... I also have to date only ever drawn like two Bay-verse designs. Unlike the BW bots, the Bay designs are by choice because I honestly find most of them ugly as sin.

So yeah, pretty much any Transformers are something I would have fun with - I also enjoy drawing Gobots and other non TF transforming mecha. (I will draw the hell out of some Rock Lords!)
