A half tube way up there? Well I can see them over shooting the tube when they get some air, and fall right off the building and go splat. since the top of the tube goes over the edge. don't take much to go wrong.
Umm, from the program palette, sometimes it takes long time to decide which one fits the best if its gona be coloring a huge area, and its imortant then to decide right. But Orange/Purple/Blue is allways look to watch at and I used some of it on the shaded areas. Never use normal and standard colors, allways mix them up, some are needed less saturated, some are needed more. Thank you ))
