Hello,
I am glad you like the design
Here are the revisions you suggested:
I made the tagline bigger by making the name all caps #51. Every logo needs to look good with the icon on the side and on the top, since for different occasions you will use it differently, for example for web it usually used horizontally, so i submit it both ways:
#49 and #50. Also the logo needs to be good looking when it is in solid color, because usually it is printed like that on t-shirts and other materials and it can look good for example on a back of a business card #52 and #53.
Hope you like the revisions, if you have other suggestions please let me know
Thank you!
