#76 is great, but darker grey and brighter orange please like #28. also play with colouring your and self differently like #54 , also try using an @ symbol instead of the word "at", WORK may be a bit large in size as it seems to dominate the logo see #53
#107 is currently my second choice so if you have time rework it a little, lower case a in At please and maybe it is a little too informal, can you make the character a little more corporate without it looking too serious. Also maybe try a few different fonts.
you are in with a chance to win if these changes hit the mark :-)
