#123 - Liking the concept of the bird! Added something new to the picture and looks cool as you've turned it into more of an abstract symbol here
#121 is going in a similar direction, but i think looks more like a clothing brand, possibly because of the brands that exist out there with those kinds of logos.
#102 and #115 are interesting to me as they're very simple and elegant. Focused on form and not too complicated.
The ones similar to #106-#108 have a bit more circular shapes for my taste, although they look nice!
Thanks so much for the submissions! Really great work
