Entry #60 is our favorite choice of what you've done. Great work.
Please play with the fonts a little.
The light grey - make white.
Make MIND stand out more than Unleashed ( looks like you have Unleashed a little larger than "the" or "mind" )
Also make the tagline more readable please.
Would like to also see the logo in two color so we can see what it will look like printed on t-shirts.
Thanks again!
