Hi! I will be doing your lesson 2 critique.

To start off with arrows the main issue you have is that while lines are mainly confident, when adding line weight your arrows start to fall off.When adding line weight you should do it the same way as you did the normal lines,slowly ghost before putting a line and dont worry if its off,remember confidence over accuracy.Its okay if you need to take time to ghost lines properly,dont rush it I say this because some of your other lines in this exercise come off a bit wobbly

For Organic Forms with Contour Lines there is a bit of wobbly lines that you should be aware of and also your ellipses tend to be also wobbly as well as not rotating as much as they should be.

Try to not repeat lines as repeated lines are a mistake like here : https://imgur.com/a/5nQTvuU

One more thing,when drawing organic form they should be kept simple, remember to think of them as 2 balls connected like a tube. : https://imgur.com/a/c4VTKsD

Texture is pretty good, I see that you mainly focused on drawing shadows.One thing i want to mention is that with your gradients there is a visible black bar,when doing doing gradients you should

try to make transition so that the viewer cant see a black (or a white bar) https://d15v304a6xpq4b.cloudfront.net/lesson_images/7d1f3467.jpg

Dissection is pretty well done,good job on this one!

Form intersection is generally pretty solid,there is again mistake of line weight and some pages could have had a bit more form but overall its drawn pretty confidently.

For organic intersection has similar problem as the exercises before,some wobbly and unconfident lines.But there is also a issue of not drawing trough out your form,from what I can see from pictures your form tends to cut out? https://imgur.com/a/XmeQ7LX

There is also a problem of form not wrapping properly and shadows being a bit off as well as from being a bit also wobbly and not sausage-like.: https://imgur.com/a/NQbpvwB
