So, you got a few of the organic arrows to show perspective, but I think you should try to compress them more and show a bit more foreshortening. You also seem to be wobbly on the arrows as well as the form intersections. You should've had one page of just boxes and done some hatching to show faces. You're lines ae extremely wobbly on the Form intersections and all of your lines are very bulky which is basically showing that you're not ghosting lines and you're too scared of messing it up. I feel like you could've done better on the texture analysis the texture is very loose and not really clear. The stone and crumpled paper looks very similiar and the crab skin doesn't look very clear either. To be fair the texture dissections look pretty good, just make sure you are making the texture implicit. For example, the disco ball texture would we considered explicit and that's not what this course wants. The ice cream texture would be and example of implicit texture which is well done there. The organic intersections looks like they had better more confident line work which is good, but I think your shadows need a little better understanding. Make sure you read the instructions carefully and re-read them if need be. I think if you had an official critique they wouldn't let you move on without any additional steps. I suggest you really go over lesson one on linework and practice that for a while. Then you should do 2 pages of form intersections again and 1 page of the organic arrows and try to focus on the foreshortening and the linework maybe even do a couple pages on the side if you have to (that's what I had to do when trying to correct mine). Good luck!
