I am still a novice at making signatures, so please give me the best CNC's as possible so I can improve:)

Sigs at the top are the newest and the ones at the bottom are the oldest.

Best way to grow as an artist is to just do as many tuts as you can and take in as much style lessons from each, grow your skills everywhere and then pick your style.
