Chris, I'm looking forward to seeing this top-heavy font in use.
The only character that really bothers me is the 'B'. The top bowl is too top-heavy for my taste. It's the width more than the height. I'd optically adjust it so it's a bit more narrow. Just enough to correct the illusion that it's wider than the bottom.
I'm designing this condensed sans-serif top-heavy font. I'd like any constructive criticism you can offer to improve the process and the look of it. This is all the letter I have finished so far...
