Whoot! I declare my hardest/longest worked on picture! Though it may be outdone soon.
I think it took about 15+ hours total, but it was worked on for the past 17 days on-and-off, so I really have no idea exactly how much time it took. Originally I started out as just a bunch of sketches of Paddy, there was also one other pencil drawing of Paddy on a swing which I decided not to add because it would've taken another few days to complete. I was experimenting with the Red Eye Bruch Tool, when I decided I wanted to make a bunch of photographs for Paddy's layout. They'll most likely be arranged differently in the final form for the layout and I want to add things like coins, pencils, and random odds and ends lying about on the table, but this is what I'm entering in a local art contest coming up in July.
