Sig A: 5/5 - 750k, great work, it gets a little noisy in the bottom right but as an overall noisy sig it doesn't detract from the rest
Sig B: 5/5 - 750k, my favorite of the bunch, clear focal point with the render, great work on the text
Sig C: 5/5 - 750k, the most simplistic looking, but still solid work with the background and not distracting in any way
Sig D: 4/5 - 600k, love the text here besides the green bleeding into the M, the neon green on the right side really draws the eye away from the focal point and drags the rest down
