I did do some zoo stuff about 3 or 4 weeks ago and I also sketch passerbys when getting high on my patio. I can sometimes come up with a nice silhouette or gesture but the fine details of human subjects still eludes me. I guess it's a matter of building up my short term memory? I have noticed since I started stuff at the zoo and people watching from my patio that I've been able to remember more features about something from a quick half-second glance.
