Really nice icon in #38 and #36 ! regarding the word geeom I'd try to change font or revert to non capital letters and would avoid grey as a colour. Would probably also try the light green you've used in #37 as the font colour.
just a question why have you used black as the background for #36 ?
Thank you very much for your feedback, glad that you like the concept :) sure will update you soon with modifications, I use dark background coz i seen most of smart phones(i phone) launch icons in dark backgrounds.
