Individigital Black

I am really glad that my font "Individigital" is quite popular, and I am trying to evolve it, so here is the first variation, "Individigital Black".Slight changes in forms and weight.These fonts are donationware = in case you like it that much or planning to use commercial donate 1-10 $. Any feedback, comment and notice would be appreciated a lot as it may help me keep going on the path of font design.
Thank you,
Roland
