Hi Arnoud, thank you for your encouraging words and for the advice,
, yes, now looking at them on the monitor as you tell me I can see that in the values I have skipped the intermediate steps,
that does not pass evenly from light to dark, that I skipped values, passages, in the iris and above I had to darken more I believe (and also in other parts that probably escape me), I'm talking about the last one I made.
After this I started another one that I didn't end up making mistakes while now I'm doing one where I will try more to practice better on the light and dark contrasts. unlike the other eyes of this reference and the next time I did a print in case I find it better
Posteri a wip, maybe there are other errors to be corrected in the phase prior to shading, or in any case independent of them. and Sparrow greeting me heartily) and after the post.
On shading maybe I have already wrong (or at least I should try to correct it I think) the part outside the cornea on the left of the sheet (dark part, I don't know if it is the limbus of the cornea, if I found the right name) the types of strokes and perhaps it is better or better to do the whole pupil lightly first and then gradually darken. But maybe it's not the time but I had to use thinner lines (maybe go with another pencil or better)
Thanks a lot .
