The common letters look better than the spiky ones IMO… they’re much cleaner and sit well together, the spikes of the other seem to clash a little
I’d lose the arrow and star for now, the E in the 2nd has potential, keep going, just do tonnes of variations and fill pages and pages. Try different angles on bars and different sizes on everything until you refine it into something you’re happy with
A couple of options here, not sure wether to persevere with the symmetrical loop on either sides or bin it and go simpler… Opinions welcome
