Well, it's been a month and I haven't taken any more photos. I'm back at work and have very little free time, so it looks like the photography hobby might be over before it really started. I don't like relying on other people, so my portait photography phase might have been doomed from the start.
It's not a total waste though, learning more about portrait photography has gotten me to think more about posing which I hope will improve my drawing. On the downside, I now look at Instagram way too much.
