Hey, @bycristian123, good job! Let me go straight into your questions: 1) Yes, pretty much! The landmarks, as you must know by now, are cue parts of the body, mostly points of the skeleton that are not hidden underneath muscles or fat, thus end up showing on the surface of the skin. When drawing the figure from observation, these landmarks, especially the bony ones, can help us better visualize some kinds of gesture rhythms and even be used as reference points from which to visualize or measure proportions. So being able to identify the landmarks is a way of building up a little bit of anatomy on top of what you’ve already studied in order to give your figure sketches a bit more structure. It’s just the tip of the iceberg, though, as there’s a lot more about anatomy to be learned further ahead, but it’s a pretty good start! 2) No, I wouldn’t say it’s necessary to place any muscles at this point - unless you already have a previous knowledge of anatomy and you feel that applying it might help you with this practice, then why not use it? But if not, I’d say it’s totally fine to stick with using just gesture, the Bean and the landmarks, and that should be enough for now. And since this practice is about us getting familiar with the names and placements of the landmarks, I think it could be nice to take some reminder notes along with the drawings, if you feel that helps. I’m attaching an example of my own to illustrate what I mean. As for your sketches, I think you may even have gone a bit beyond just landmarks, since your sketches already shows hints of form and mannequinization. This is not an essential part of this exercise, but if you are comfortable incorporating it, then great! Hope this helps. Keep it up!
