I think so. A lot of the times, some of the concepts don't really sink in until you have more experience just drawing. The fundamentals are simple to understand at face value but actually applying them successfully in your drawings takes a while.

When I look at some of my really old terrible art from before I began to actually study how to draw, even without knowledge of the fundamentals there is a slight improvement just from the time spent drawing and trying to figure out how to draw things. Sometimes you pick up the fundamentals without realising it just by doing this but it is a much slower process of improvement and you can end up with gaps in your knowledge. Combining drawing for fun with conscious effort to study the fundamentals and applying what you learned to your fun drawings, you will surely improve :)

Yes. But don't worry about any of that, just do the work and see for yourself.

Hi,

I have been doing these along with gesture drawings and honestly I know I improved since now I can draw what I could only in side view, in 3D and any direction. it is not as good since I just completed plants and i'm into insects but even my snakes look better (since I use a method similar to the branches). I am sure that after the next subjects I am just going to get better at it. Also, the strengh of the construction method is once you've drawn the same thing object/ animal in different positions, it's actually easier to draw it from imagination. Try it with a branch and leaves (since that's the lesson you last finished) and you will see.

Have Fun!

I havent completed this course yet but I have done other stuff and gone through the dreaded "how to draw" book, so heres my take on it for what its worth.

You begin drawing as if you are feeling the form as you draw across the surface of objects, have in mind that the centerlines and lines of action often represent the axis of an ellipse that give you the volume of a form. Gesture and structure need to become a way of seeing as well as a way of thinking. Whilst the technical ability to perform these lessons and tasks can be done quite quickly, the realisation of how it applies to drawing in other situations can take some time and is just about pencil mileage and beginning to make connections between these teachings and other things you have learned. for a long time it feels like you are learning little bits of things that are unrelated but at some point there will be clarity where you can see the synergy of all the learning and efforts coming together in your art. If you have experience in figure drawing you will probably have felt the frustration of learning gesture drawing, and then learning construction/anatomy and being held back by the limit of your knowledge in either of both topics and having to go back and forth between the two approaches until you can advance in the other. This is very much like that, learn the principles and have it in your pocket as you push forward and eventually you will realise how to apply it.

In other words, it sounds like you are doing fine, as long as you are drawing with intended goals even when youre just experimenting or messing around in your sketchbook you are probably advancing.
