The first one is better, but they do look like the same person. Try it in a mirror, from life. It's harder, but you learn more.
The most striking characteristic is the upper lip. My mother said that profiles where the upper lip sticks out farther than the lower lip were "old fashioned." It was certainly a kind of face illustrators liked at the turn of the last century.
I was once on the receiving end of a critique so savagely nasty, I marched straight out of class to the office and changed my major (sketchbook).
The first one is amazing, I'm very impressed with the values and overall form, you seemed to have nailed it! I hope you'll continue to update this, you've got such a fun and interesting style
i do like the first one more, however they do look like the same person. Nicely executed
