#2 is ok with its simplicity. i like the marks you made that look like knife slashes. the logo should not be mainly a bat. i would say figure out the rest of the logo and forget about the bat wings for now. i dont like the font and lettering.
#50 - could you put the word EVOLVE below the shield. get rid of the flames on the shield. and fill the shield with some other concepts? maybe a stylized E or something else? Id like to see different creative ideas and I will continue to give feedback. Thank you!
