#30: I like this look a lot! Maybe the 'interior design' portion could be a little lore narrow to give a slightly harsher edge to the logo?
#27: I really like the 'SEI" potion of this! very creative! As much as i love the color, i think they are a little to playful to cover all of the various markets i'm trying to reach, so maybe if yo don't mind trying with some deeper ranges of blue, grey and green?
If I am not wrong you are looking for more of squarish and rectangular feel of logos and those that are defined kinds rather than abstract shapes...right?
