#20 symbol is edges are too wispy. Prefer solid. #21 Could make solid symbol #16 - cool design but like the "Root and Foundry part stacked and to the right of the symbol.
#49- Layout is great! change font to match #38 font, change Words to match #52. I like the double stacked words and the & symbol instead of + symbol. Change color to match colors of #27. I like the bold crisp look.
86 - Love the colors scheme and design. The symbol is very cool. Can you make the border of the F slightly thinner. Maybe about as thin as the symbol in #62. I think that the "R" should keep a constant width as it wraps around the F. I notice on the right side it gets much fatter. Also the diagonal split you have in the "R" from upper left to low right doesn't seem to flow because it jogs. See what you can do to make it look like it flows more. I hope I'm not too confusing.
