The #8 is very nicely done. Possiblly try a darker color for the surveying, inc text to make it stand out a bit more. The #10 has a great logo for web and mobile applications. Possibly add a white text/black rectangle design instead of the blue text. The #9 design resemble too many other company logos. Right idea but not unique enough. Thank you for your designs.
For # 8, can you please place the surveying in either a black rectangle or a navy blue triangle? For # 10, # 30, # 29, and # 28, I am not fond of the light blue, can it be changed to a dark to medium grey?
OK. Many thanks to ended this contest early. Please wait 15 minutes... I will send the final file :) So you can approve the final file to release prize contest.
