I am very pleased with this experiment, and even moreso that you decided to take photos at various stages of the drawing, because that ended up highlighting both specific strengths and weaknesses with greater clarity.

There are two primary issues that come into play when it comes to why you're struggling with drawing:

• As I suspected, you don't spend enough time on your drawings. This time, you did - and the result is a HUGE improvement over everything you've submitted to date. This second-last stage, for example, is extremely well done. Construction is being applied very well here, and you've exhibited a lot of care in studying your reference and ensuring that most of the marks you put down were directly informed by the reference image.

• When you add your additional forms, you're showing signs that you're still thinking very much about how this is a two dimensional drawing, rather than a three dimensional object. You tend to pile the additional forms on top of the antelope's back, but don't consider how they actually wrap around its structure, not just remaining on top but also wrapping around the creature's sides. I've drawn on top of your construction here to demonstrate what I mean. Pay attention to the difference between my additional masses and yours.

To that last point, you mention that you abandon some drawings after a short while because of a mistake or an issue with proportions. Don't. What is being asked of you here isn't to create a perfect replica of the reference photo. What we're doing here is an exercise, an exploration of the animal, how they're structured, how they can be broken down into simple forms, and how those forms relate to one another in space. I have had ample situations where students have submitted drawings that were proportionally hilarious, but where because the construction itself was well established, it looked like it was still real - despite being malformed. As though the student had accurately captured some abnormality.

Now, let's take one step forward. I want you to do 5 more animal drawings. Of these, I want the first three to focus on the core construction only, no additional forms at all. That basically means ending at this stage. You're handling this well, but I want to make sure that you grasp how to go about it and a single drawing isn't quite enough to establish that.

Once those first three are done, I want you to do the last two taking them as far with construction as you can, pushing the use of additional forms and all of that.

Again, take your time. That is the primary issue that has always held you back, and you've shown considerable progress here in pushing yourself to invest loads more time into observing and studying your reference, and into planning and preparing each mark.
