#1 - Thanks for your hard work. I like the colors. However, in letter "O, there is a symbol of electrical outlet which represents electrical house supply, not to electrical power transmissiion. Our company focuses on extra high voltage electrical transmission system. So, the symbols like a transmission tower or an electrical thunder might better represent our company. Also, it might looks better if the letters should be thicker.
#6: I like the thunder, the globe, and the overall layout. However, I wonder what it will look like if the color of the thunder is orange? Also, can we try a font similar to the one used in #7?
#12 - I have some idea for your consideration. I wonder what it will look like if the "P" letter in "powergrid" is slightly bigger than the rest letters. Like 15-30% bigger.
We really like the design of #12. After discussion within our members, using entry #12 could you please try to shift the lightning (thunder) to the right, let say to the 1/4 position and 1/3 position. Thanks.
