I don't mind you doing a crit based on the quality of the painting,you can call it a load of crap if you like ,I guess I wouldn't be selling you a print anyway!. I merely pointed out that the smoke can blow contrary to the direction the ship is travelling. Trains on the other hand are often doing 50 to 80 Mph and the smoke is quite likely as you say to issue straight backwards. perhaps you'd prefer this one (its correct by your estimation).
