Thomas's sketchbook

Try to apply the concept found here by drawing simple line and alternating the quality of your line making also not the degre of inclination for each mark if possible to give yourself some room to replicate those type of mark making.

 
    Thank you for the image, will pay attention to "how" i put down those marks. Didn't think of this one, so worth giving it a shot and practice it. Also, i am, unfortunately, aware of the issue. I think, at least, that you are referring to what i see. More below, to have some context, coupled with the windy paths of being "self thought" .

    I see you have found my "Achilles Heel", so to say. Yes. I am inconsistent. Over the years, had a lot of different resources, and tutorials, showing me a lot of different approaches to doing the same thing, and it shows. Just an abridged timeline of where i was learning from, can be read below - not excuses, just so you know i am aware of it, also a bit of a tutorial review, to occupy the other millions out there on the internet already  - : 

1. First learned drawing proper observational drawings was from the book "Drawing on the Right Side of the Brain".

Advantage: Fell in love with drawing, and used a lot of concepts, without being aware of them.
Disadvantage: Observational only. The "Theory" part needs to be taken with a grain of salt, of course. Good to explain the basic idea tough.

2. You will dismiss his name, because he is considered bad among forums users(especially conceptart.org had a beef with him, if i remember correctly), but, first time i learned the human proportions, and anatomy,  was from the old tutorials of Riven Phoenix. 

Advantage: The "for dummies", and drill-like re-draw, approach made me learn a lot about the standard artistic proportions, to which i am still instinctively falling back to, today. 
Disadvantage: Stiff as hell. - didn't know about gesture concepts at all, back then, tough - 

3. Andrew Loomis, and Vilppu. This is where i realized why my drawings were stiff. After this, i trail off into a lot of directions and online resources.

    To cut the wall of text short, i have a constant internal conflict, between the extremely gestural and structural because of this, and it shows. When i can commit, in some of the cases, from the sketches, it can be seen, i think. At least a bit of increase in quality is visible. When not, well...Easter Island statue approach to drawing. Also, i have a bad habit of increasing drawing speed to ridiculous speeds. I wish i was joking, but, i think this is due to the sped-up tutorials seen on Youtube.  I slow down deliberately, although, when i forget myself, i still realize  later "wait, this isn't a 30 second gesture drawing, slow the $$@@ down!!!!".
