The new shade of yellow looks very nice with the design.
Now that I've looked at it some more, I really like the way the feet are designed. The larger feet combined with the digitigrade styled legs makes for a very powerful looking lower body visual. I bet he could stomp some 'Cons.

At the same time, I could imagine the parts of the lower legs shifting to go in a more "roller skating" look like movie Sideswipe for some major speed.
Aside from the cannon arm and the fact that yellow was used as a primary body colour, I don't think it resembles BB too much, if at all. No more than G1 BB and G1 Sunstreaker.
I really love this design!
