Arrows:

Your arrows are very good your lines are long and smooth and I noticed how you began to employ more perspective as continued doing your arrows

Sasuages:

Your full ellipse sasuages have some problems. First most is the center line is very off with some of them and your ellipses because of this it is conflicting with the orientation of your minor ellipses. with your center line. Another problem you have envolves the ends of your sasuages many of them taper off. Don't be afraid to draw your sasauges in parts and ghost your lines. You want them be as close to equal sizes. You are doing good work with the amount of ellipses you are using.

Half ellipise have many off the same problems except with the number of ellipses. The sasauge in the bottom right corner has to many ellipses and with the center line being off really disrupts the form

Textures:

Your texture are a little inconsisten but seem to grasp the idea behind them. Your texture analysis needs more work with detail density You need to work on detail density on your texture studies. Think of detail density as 10 lines that seperate the box. 10-9 being most detailed and 1-0 being the least detailed. As you cross those bounries the deatil has to decrease in levels while doing so you should strive to make it as seemless as you possibley can make it.

Your texture sasuages follow the same issue because of your lack of detail density control it fells like some times you are operating at level 10 at all times which makes it feel like you are doing it explicitly. Addtionally their is the issue of contours you seem to be struggling with making with wrapping your texture around the form. Don't be afraid to rotate the page to grasp a better sense of how it is sitting in space.

Form intersections

Your inorganic form intersections ar very good just rember to be consistent with your perspective and remember to put more emphasis on and lineweight on the connection between the boundries of the individual forms and where those forms intersect.

Your organic intersections are very good you are keeping the shadows consistent. addtioanlly place more line weight on the outlines of the sasuages themselves so their form intersections don't clash with their neighbors.
