Nice work on those liveries Ukraineball, although I think the 2000 Delta livery (Colours in Motion - AKA the waving flag livery) could use some additional attention. Right now the shading on the waving flag looks like it was made using a wide photoshop brush in an approximation of how it looks in reality, but I think a little more refinement could be helpful.

Keep up the good work!
