I didn't make a major change, I just noticed that my original entry has some rough edges on the sides (I mean not a perfect circle). I fixed it then I adjusted some colors and the font size to make the silhouette of the meditating human a little more visible.

I included my updated version of the logo in my original post. Here is the link to see the before and after logo.
Tribe Steem Up Logo Contest: My Entry
Thank you so much for considering my creation in one of the chosen eight. Everyone shares an excellent logo, whatever the result will be, my heart will be forever grateful for this opportunity.

Have a great day and may the God be with us all the time. :)
