Recently I've vastly improved at portraiture, and for my day game I just pick a high traffic spot in a park and start drawing, and people stop and talk to me. Fairly often, if it's a hot girl I'll chat her up and end up drawing her portrait. This also comes up with girls I've met randomly. The last couple of times it's like I've discovered a gold mine or something. Not to sound callous, but easiest lays ever.I get to have her undivided attention, be the one in charge because we're interacting on my terms. There's tons of eye contact, ample opportunity to compliment her looks if I feel like it, and I'm in her bubble because I get them to sit in front of me then I lean in close to get a good look.The easiest ones have been where I knew the girl from a random conversation before or something. Today I was wondering if it would be as effective to just approach hot girls and ask them of I can/tell them I want to draw them. Would this come off too obvious? Does it sound like the preamble is integral? Any suggestions to make it even easier?
