Hi @John Carter. I think they are nicely done! What I get from your write is that you don't like the lack of character of most of the heads, you need to look more for reality. If you are used to draw from imagination, the best way is to improve your consumption side and add images to your visual library. If you do not have any problem on trying to draw from observation, just go for it too. Also, if you want to "feel" the solidity of form or you prefer going for something with some kind of structure, go for learning what are the components of the head, from bones to muscles and skin and fat (only if you are not doing it yet. I am supposing you got used to use a really specific combination of basic forms, like a manekin. Idk). I recomend to play with references. Analize them from observation and drawing, as you prefer. To go for a perfect copy or use them as inspiration is up to you. Hope it helps. Sorry for the long text, keep up the practice!

@John Carter I agree with @Yngwie and I think these actually look pretty good! They feel loose and sort of quick (in a good way), but then they also show a nice solid sense of construction (and that’s not an easy balance to manage). Good job and thanks for sharing! And yeah, the guy with the open mouth totally reminded me of one of Rockwell’s illustrations too. 🙂

Hey!, I am definitely not an expert but I wanted to say that i think that your sketches do not look like manikins at all. They have expressions and they look like they are in ‘movement’. It is good to be critical of your own work but don’t be to critical ;) but it’s also easier to be more objective about someone else there work then your own. I hope this helps. (Again, I am far from an expert)
