Nice work! I like your solar observation form and those close ups of the three active regions, too. With that scope you have an excellent set up for white light solar observing.
Looking forward to your second sketch.

Beautiful first sketch. Very interesting the three isolated regions. Nice presentation.

Peter, your drawings on the It.forum was very inspiring to me.

Thank you Michael, as for the technique I have followed this tutorial:
While here is the observation form that I actually used:
Well, you have picked some very good sources to refer to, but are you aware that Alan Strauss's tutorial is for sketching the Sun in H-alpha, not white light? He prepares his solar disk to render the Sun's chromosphere, not the photosphere seen in WL.

Of course, as a newcomers, I'open to all of your excellent advices (of course, please, don't tell me to buy an h-alpha scope or, better yet, tell it to my wife )

I had an idea you might be able to see solar granulation with a six inch refractor and were trying to render it. I usually can't see granulation well enough to do anything about including it.
I would also suggest that you look for the limb darkening that is usually apparent in WL and also faculae if any active regions are near the solar limb. Faculae are not always detectable if the seeing and/or transparency are not good but the limb darkening is usually visible. I believe you may have seen some faculae and included it.
Anyway, your drawings are excellent and much better than my 1st and 2nd attempts.

Limb darkening was not as obvious however.
