Hi NICOSOSALARRAIN! First of all I have to mention how clean your arrows are like wow! The only thing I can say is donlt try to go over any incorrect lines with lineweight. For your organic forms, it seems you tried to play around with the consistency of the middle area which is good but not allowed for the homework. Try doing some in your own time! Some ellipses are misaligned. A good amount of them have no change in degree (they all stay the same size.) For the textures, I could critique better with reference so please post that as well. Sometimes it looks like your just scribbling or not drawing shadows and just lines but I can't tell with no reference. I would also need a reference for dissections, but it isn't as vital. For form intersections, try to make the intersections follow the contour lines. I saw this not happen the most in boxes (mostly first page.) They're 3D not 2D! Don't redo your ellipses if they are incorrect. Go through 2-3 times no more. For the organic intersections, it seems a little flat. Your contour lines are too flat and don't change degrees. They are rounded sausages not rectangular prism like ones. The shadows on some are flat as well. Great Job! I think you did great with some hiccups here and there.
