Did this mural at school last year. Took quite a long time since I didn't have much time to go outside and work and do my regular assignments at the same time.
Had 3 other helpers but they weren't too experienced in painting so I ended up having to fix everything they started on. =.= so yeah. But they were a lot of help just getting things started when I got lazy.
It doesn't look too large from the photo but the dimensions of the panels total were about 6 feet high and 20 something feet long. Didn't measure it. LOL.
The high school is currently going through construction so I don't know if its there anymore. They said there is a high chance of it getting knocked down so this photo will probably be my memory of it. :[
