Hello Arnould, I'm sorry if I put it here but in the other classes I think I would be completely off topic, I wanted to write one last thing here and then step to 16, (I did not do exercises but started to study explanation examples).
I wanted to tell you that I made 2 small purchases in recent times, I'm sharing because I think they are nice and maybe even useful for some classes, during some exercise maybe a mirror for verification ... (mirror and head of 10 cm).
small bust is for the top of the figure, for head, for now I have not used it in reality and if in time I will do its proper use but maybe I want to use it for fast sketching, look better off for what you were saying shadow even without drawing it and in the future maybe when I do not know what to draw or I would like to try to improve as much as possible in drawing head seems comfortable (yes, presents the muscles and construction for € 9 seems excellent and nothing, I was looking for something like that for any exercises on part of the figure so I am very pleased to have it).
The mirror the other purchase that has various benefits in fact although probably is widespread in art and design I confess that I ignored this (and ignored the possibility of finding errors through mirror) so it is good.
So initially taken to try to find the errors even if I'm discovering the same thing for the photos, indeed, in the photos errors I notice them at times but especially if I have already published them though,
in fact I notice them above all because first you showed them to me , seriously, it is an idea to which I arrive late but convenient for more things.
Speaking of mirrors, I had read a couple of curious articles on the black mirror (I ignored this)
I wanted above all to send you article after reading it, but I do not know if you can share external links and this is also off topic, I thought to ask if I could send you private message in case but I lost the link in the meantime, it was an article a few months ago who talked about some recent discoveries, I do not know, but the explanation was very exhaustive, I can not find that article but I found this that basically is similar (but you probably already know the existence of CLAUDE GLASS / black mirror and use in art, however, the title of the article is nice and also speaks of a book on the subject)
The Claude Glass By RAYMOND J. STEINER
ART TIMES December, 2004, I'd like to find it 1 black mirror in some DIY store or small black mirror one, intrigues me in fact because light, shading is both a thing of the most important things that one aspect learn better, dimuinuire errors and lend more attention
