hello
thanks for the feedback
v2, tweaked to give it a bit more pop

#18

The bottom right edge looks a little bit like there is a wobble, can this be smoothed out?

The top edge (where the white shadow is) looks a bit like it is tilted down especially when see small. Can this be avoided.

Your design is very professional, both gentle and stong. But, I'm thinking I need a stronger image. Any ideas?

new concept

#18 and #40. I so like your work, the first one was subtle, which I asked for,
but then when I got it, I realized my direction was a little misleading, then I
asked for strength and felt you really got it with this latest entry, but in
#40, the stacking of bricks kind of loses the point of exponential change, can
you go back to your first concept, but sharpen the color and use the stronger
typography as in the second?
