i have a old model of an airbus a340-its the first model i made and i have quite low expierience with 3D modelling, i dont know how to make more segments for the cylinder part, and i always used the default 12 segment cylinder, so its low poly for everything, the whole plane is blocky... as i model planes more, my skills got better and i can make detailed planes, i can make detailed planes in one day, but i made this in three days because im getting bored with 3d modelling and started to take my time in to this kind of thing...
so here is a comparison between the new model and the old model-the old model has a boolean cockpit window cutout and the new one has a knife cutout cockpit window... thus see the difference between the two models!
