Well, he told me he tried to do his best for this batch of work and he took a lot more time lately (40 days per batch compared with some 20 days in the past). This up-stepping might have been the result of his participation in a social media group I setup earlier this year:
www.facebook.com/.../328180933868932
where he can post WIP pictures and socialize with friends, colleagues and admirers. He saw their works too and I think he just wants to show them his best effort. All the photos that are posted were taken by myself. It's a pity that though I spent so much on models and modeling services, I paid very little on camera and equipment. I'm still using under $100 digital camera (GE A1250 12.2MP), a very good one. It's two years old, I dropped it twice but it survived both.
