This is going to sound nit picky but the red in the bottom part of the loop in 136 is darker, which I do like better, than the red in the bottom of the loops in 143 and 144. Could you modify 136, using the same red it already has and make the word JET red with a black dash between the words JET and TECH? I know you said you already did that in 143 but again, the red in the loop in 143 is not as dark as the red in 136.
Once you do this, could you also submit the same logo again except with a longer loop like the one in 144. This too needs a black dash instead of red and should use the darker red in the loop.
Then, simply as a comparison, change the color of the dash in 143 and 144 to back and please leave them the way they are.
Thank you.
