Very cool scene Momcha. The bright colours of the truck and the grafitti contrast nicely with earthy tones on the ground and in the rust ... so it would be a real eye-catcher on a competition table.
It appears that the tower was painted with techniques rather than "effort" ... some hint of mortar between the bricks would have given this so much extra. How it stands now ... especially in the photographs ... the missing bricks stand out, as does the joint on the left hand side (see image below), where the metal ladder appears to be the same brick colour. They should have more metal effect. Painting in the mortar may have hidden this issue?? This is on a nit-picking level ... its a great work, but this is the area that could have lifted it even higher in my opinion.
