Thank you...wow, you are fast :-) Just a quick feedback, I think I like #54 better than #55. It is more optimistic and lively. the black background is too sad. So I would suggest to continue with #54 and
#49. Can't decide which one I like better, they have both their pros and cons:
#49 is very shining, optimistic and clear.
#54 has more depth, more passion. Maybe there is something you could to to make the icon and the letters stand out more in #54?
In both I like the brighter center and the darker angles. Would maybe work with #52 as well?
Thank you for translating my wishes into new entries so wonderfully!
