#78 the shield is interesting. Could you make it without the horizontal curve through the shield? That may give a different perspective I may like more. #79 and #80 are cool shapes in colors I like for the logo (blue and green) but can you make the design say "technology" more?
#141: Can you please make a new version of this one with the color scheme you used in #130? I hope to see more contrast between the two colors in the triangle; dark blue and green.
