Hello JuanSebastianPulidoVelasco, I'll be giving you feedback on your Lesson 2 submission.

I have noticed you have gotten a revision request on the 250 Box Challenge to construct another 30 boxes, considering the critique. You will greatly benefit from taking adivse from this community.

Now for this critique. All in all you do show an effort to get some mileage under your belt. Please read and watch all instructions carefully to get the best out of your time.

• Let's start with the Organic Arrows exercise. Your arrows are conveying too little depth.

  • There are two reasons for that. First one is your insecure stroke. At times you fall back to "chicken scratching" you lines. Better move your pen from the shoulder. Make sure to incorporate a lot of Lesson 1 exercises into your 15 minute warm-up.

  • Secondly your arrow width does not vary enough. Looking at the sample homework here, you can see the arrows differ greatly from one end of an arrow to the other. While you start your arrow small in your submission, it varies only slightly. You don't have do keep space between individual arrows, so go bigger with them. That way you can construct large arrows, with more confident strokes.

  • I'd suggest you mimik the arrow from the exercise page and construct a few similar for the start. Only apply twists and turns once you feel confident to convey depth with your arrows.

• To the Organic Forms with Contour Lines exercise

  • The sausages have a good form: plain and simple

  • One side of their outline is confidently drawn for the most part. However you do tend to slow down and the lines become insercure at some point. For every element you draw in this course, make sure to always use Ghosting. Then commit to your sausage in one smooth go.

  • The same goes for your ellipses and contour lines: carefully plan ahead, only then apply the stroke. Try to incorporate Tables of Ellipses excercise regularly into your warm-ups. Also make sure to always draw through your ellipses. While you do this for some ellipses, for others you don't. Always do two to three rounds per ellipse.

  • Concerning the exercise execution in specifically, your degrees are all the same throughout your sausages. This does you little favour in conveying a 3D impression, which in turn is the main focus of this exercise.

• For the texture section of this lesson, just keep at it. Be careful to observe the texture for longer than you actually draw it. You rely heavily on lines and not so much on form. One good example from your Dissections is the stone wall, where you do incorporate shadow to reveal the form. This is opposed to the Log texture. There you indicate the texture only by couple of elllipses. As stated in the purpose of this exercise try to go from looking at your reference to aktually studying it.

• Next to your Form Intersections exercise.

  • The cones, spheres and cylinders look consistent throught each page. As stated above you should vary the degree of your ellipses a little more, to serve the 3D impression. This is also true for your cylinders.

  • Where you really do show a deficit is in construction of boxes. As I mentioned in the intro, you will benefit from 30+ more boxes before moving on. Or as Uncomfortable states it here: If you can draw boxes consistently, then you can construct any other form within the space enclosed by that box

• Lastly for your Organic Intersections, the points above concerning contour ellipses are also true here. However you do keep your forms fairly straight forward. Which is a plus. And you do wrap them around each other. Here and there they could wrap a little more closely as shown here, but this will come with some more mileage. One aspect to improve is to also wrap the shadow around the underlying sausage. Read this for more info

I suggest you try some more elements of the individual exercises from Lesson 2 before moving on.
