## 25 Wheel Challenge

##### 9:30 PM, Sunday June 7th 2020

Hello,

Here is my submission: https://imgur.com/a/Zy9xf03

I have difficulty in drawing the elliptical shapes, since I only have one ellipse guide that has only one degree and had to freed hand most of them.

I did learn a lot from this lesson.

Have a wonderful day!

It sounds like you have one piece of a larger ellipse guide set - they'll come in sets of many different templates covering a wide variety of sizes and degrees. Since these are quite expensive, however, most students opt to get a "master" template which is a single template with many different degrees, restricted to two or three sizes (usually on the smaller end), like the one listed in the Drawabox recommendations page here.

Looking at your wheels, many of these have been constructed quite well (despite only being able to use an ellipse guide on certain ellipses and having to freehand the rest). There are definitely several that fell apart - like 16, 17, 20, 23, etc. for example, and these are mostly due to the elliptical shape itself getting deformed. Make sure you're drawing all your ellipses from the shoulder, applying the ghosting method and ultimately executing your marks with confidence. Larger ellipses are naturally more challenging, and they're that much moreso if you end up drawing them from your elbow.

The last point on this topic I want to make comes in the form of this diagram. Notice how on the right side, we still get the sense that we're looking at a box form even though there are no internal lines defining the side planes of the form? This is something to keep in mind - you can imply specific aspects of the faces of a given form purely through how its silhouette is defined. This saves us on linework that might otherwise clutter a drawing and make it noisy/distracting - which is another benefit of working implicitly through cast shadow, instead of with lines, outlines, and other "explicit" elements.

Towards the end of your set, you end up drawing certain tire treads more like the example on the left - again, this isn't working implicitly, since you're still drawing on the textural form itself, rather than implying its presence through cast shadows on neighbouring surfaces. That diagram should help illustrate the difference.

Aside from those points, you are still largely doing a good job, and you've got a number of well constructed wheels throughout here, along with some great work on the various rims. As such, I'll go ahead and mark this challenge as complete. Just be sure to keep these things in mind, and consider picking up a master ellipse template for Lesson 7. It will come in quite handy.

Next Steps:

Move onto lesson 7.

This critique marks this lesson as complete.

Thank you!

I'm in agreement with you on the points you made, I will keep an eye out for these.

I will get started on the next one.

Have a wonderful day!

### Pentel Pocket Brush Pen

This is a remarkable little pen. Technically speaking, any brush pen of reasonable quality will do, but I'm especially fond of this one. It's incredibly difficult to draw with (especially at first) due to how much your stroke varies based on how much pressure you apply, and how you use it - but at the same time despite this frustration, it's also incredibly fun.

Moreover, due to the challenge of its use, it teaches you a lot about the nuances of one's stroke. These are the kinds of skills that one can carry over to standard felt tip pens, as well as to digital media. Really great for doodling and just enjoying yourself.
