28 - I really like submission 28 and the combination "ef" symbol. I like the 3-dimensional effect. I like the typeface choice as well. Can I see some variations with colors and 3-d effects on the type? Also, what if the type and the "ef" symbol were closer to the same height?
35 - I like the stylized "f". Can I see a version with some colors and 3-d effects on the symbol? I think the circle is supposed to be an "e" as well as an "f", but I don't think anyone can see that without studying. Can you do something with colors to bring out the "e"?
30 - I like the two-tone and 3-d effects on the "FE". I also like the color combination. I don't really like the way the "FE" looks, but I think the color and 3-d effects may have use in one of the other versions.
