Yes, this looks awesome!

I ran this image through the value study tool (https://www.proko.com/values). It makes real easy to see the larger value shapes. That would be my main critique, is to focus on designing your shapes rather than drawing what you see for this exercise. The concept of the thumbnail sketch is to help you identify values in a composition, so it would be beneficial for you to include the entire image when you are making these thumbnails. This is a cool image to work from!

Overall, I think you've done a great job separating your values clearly and you have a nice balance of big, medium, and small shapes. Your shading is also very nice and clean. I think you could make these thumbnails even better if you work a little smaller (to prevent adding too much detail) and think more about big swatches of value rather than focusing on the exact contour of the shapes. So you will be thinking more about the size, value, and placement of a shape rather than what the shape itself looks like. Your shapes are nicely designed and could be even better if you added some sharper corners to them in places, so that you have a balance of straights and curves. Great job! I am no expert on anatomy or figure drawing but I have heard Stan advise to do figure drawing before anatomy, as the anatomy course assumes you already know some concepts that are covered in the figure drawing course. Hope this helps!

You did a good job with both games, but you gave him two right hands! That arm that is reaching over his head is in a very usual position so it is an easy mistake to make. In terms of how long to spend on a topic, I'd say when you get consistent results with your attempts. Always good to revisit, and if something isn't clicking you can always try something else and come back to it. Sometimes a fresh set of eyes is all you need. Good luck :)

Oh forgot to crop them oops, these are also in order by the way. So the first one is game 1 and so on. The first one definitely has the most problems haha

I thing your lines are spot on, if this is your first attempt, you should be on the right track each and every step.

Your work is wonderful, what every you are doing is working BUT, If you are doing to many things, like me, then I try to do one thing for the class a day, just one small assignment that it is asking us to do,. You do not have to complete it, but complete 30 to 60 min of work on the sketch project, and then move to something else. I did not sketch for 30 years because of my service in the US Army. But after I retired, I decided, I wanted to get back into it, so I took a few simple on line courses to remember some basic skills. Just a few days ago, I added this course and try to sketch at least 1 hour a day. There are many distractions but most of the time, I can get t-2 hours in, and sometimes more. Some days are better, some days not so good. But, I am slowly moving forward. Good Luck!

Wow your form skills have improved drastically! So cool to see how good you become in 3D - good job! I do struggle with form so is there a video you would recommend that help you out with bending and angleing those forms or is it just practice?
