Self delusion, or the difference in five years?

Ok, I painted the self portait on the left about five years ago, and yesterday my new friend Vitali Komarov, a painter from Russia and living in the Czech Republic painted the one on the right. So which one is me? I guess they both are. I like the confident self portrait, but I definitely recognise the more reflective sadness of Vitali's portrait. I of course now want to do another self portrait...
