Hi, Red!

My apologies about the inbox, and also for missing your post.
I am so delighted to hear that you are drawing again, and if I have played some part in that, I am very gratified!

I'm most happy to share anything I can about drawing, and if nobody minds, I'll (happily) give whatever lessons I can:
We'll concern ourselves here with
Technical Rendering (since that's what you're asking about).
The thing to remember is that it is all a
process. You start, change, then stop, like every action in life. Anything you do, is composed of these three steps.
Step one: START: You have an idea. You begin with the basic form and shapes....
(Technical aspect) You get a sketchpad or something, and begin sketching away in pencil, not worrying about getting it perfect, just have fun...lotsa lines, sometimes you get messy, sometimes you get it pretty quick.
Now you've got your basic form and shapes. Take a black pen and go over the pencil mess and get your lines established just the way you like.
Step two: CHANGE: What I did next is to take a piece of really good paper, and trace the "good" lines onto it in India ink.
(Technical aspect) The paper is 100% rag paper, which takes marker really well; it doesn't "bleed" and the colors show up "true". The markers don't smear the India ink, because the ink isn't affected by the markers. Or anything else!
BTW, at this point, I fasten this (very thin) paper to illustration board...that way, it doesn't rip or warp or curl...I use Scotch #77 Spray-mount. Now I have a substrate that will stand up to whatever I do to it next. The picture is laid out in fine lines, just waiting for the first splash of color.
I used markers to "tone" the pic, then Prismacolor pencils to add "fussy" color accents and textures. The hard white details are paint, called "Designer's Gouache"...this is kind of like poster paint (tempera paint) buts comes in little tubes, and is much finer. It's also really easy and fast to use!
Step three: STOP: The hardest part for an artist, LOL!
At this point, you kinda know that it's there...the hard thing to know is WHERE to stop, and many an illustration has been ruined by "overworking" a piece. I guess you just have to do it enough times to where you know where that point is.
Anyway, if you view the creation of anything as a series of processes, you will see right THROUGH the steps, all the way through Start, Change, and Stop.
(This also applies to how you run your life, too.) Hope you liked this, and I hope it helps.
