Small looks weird with all those boxes sticking out of the chassis. I get that they're to cover up components that are otherwise sticking out of the chassis, but couldn't you make a larger chassis? Or at the very least, try to make the boxes blend in more with the rest of the robot.
Abomination II, to be perfectly blunt, just looks ugly and messy. It looks like something cobbled together from bits of LEGO, rather than an actual robot. You should use a Perm to power the bar: it'd be much simpler and easier, and would make your bot more powerful and better-looking, since it wouldn't have that giant box sticking out of the front.
It seems like you're trying to make your chassis as small as possible, which is admirable, but you're making them too small and running out of space, hence all the ugly boxes sticking out all over the place. It's better to start with a chassis that's too large, and gradually shrink it down, than to start with a chassis that's too small and haphazardly try to cram as much as possible into it.
