Seth in numbers 55 and 57 I would delete the shadow at the bottom as it will be a challenge to get the reproduction correct. Also we want to overstate "Enterprise" and understate "PCS" Thanks
#68 is good but the "pcs" is the same size as the "Enterprise" I would try to make the "Enterprise" more dominant than the "pcs" thank you for all your work.
Also #69 is good. Do everything to it that you have done to #68 leaving the icon unchanged with the blue colors. Thank you
