Meh, I like the concept and idea, even if it's not allowed.
Unfortunatly I think this MC needs a lot of work, mainly in the main body. The large round pieces coming out of the sides of it's legs look too much like an AT-ST. And honestly, I'm going to be truthful, an scout walker just doesn't need to be motorized. Sure, it's creative and you(two people?) seem to have a talent in that way, but you did it with the AT-ST. This is a bit of a copy, and it's slightly boring. A scout walker is meant to be small and detailed, and not large and sloppy. Quality is always over quantity when it comes to lego.
I am, however, curious as to your "puring" of a new driver.
Welcome to EB, BTW, make yourself a welcome topic and tell us about yourself(s)!
