If you want to achieve reading from a distance and reading when very tiny, as you said, you need to lose that font. Those fine lines in there will disappear from a distance and be too small to see when it's "tiny", will end up being a single strand of thread if you have it sewn on a shirt, etc.
I went to a quote a job about a year ago. They needed pan faces for their street sign, and then signs on their building. They handed me their card and the entire thing was in a font like that. They insisted on keeping the font. I insisted no one would be able to read it. I refused to quote the job for them in that style font.
Drive by there 3 months later, I see the sign, you can't tell the name of the place or what they sell. You literally can't read the sign while driving down the road. I've been by there many times since and I never see cars in their lot. Not because they don't have a good business, but because no one knows they are there because they can't read the freakin' sign!
Thicken it up!
Disclaimer: I'm not a graphics designer, don't know anything about graphic design, and don't pretend to be a graphic designer, but I can read from my car while driving down the road (if the sign is clear enough to read!).
