I think it would be useful if there was a lesson on gridlines like the ones used on Robby and Rob.

(http://www.drawspace.com/lessons/lesson.php?id=w05)

And also on more on crosshatching, because I find it hard to crosshatch large areas and sometimes lines appear darker than others (even if I'm applying the same ammount of pressure)

Thanks! All the tutorials so far have helped me

yes

If you search online, you'll find endless descriptions of how to use grid lines to enlarge or reduce drawings.

Speaking of gridlines, I would be really happy to see one of those cool drawing puzzles, where there are parts of a drawing mixed up and labeled, and we have to draw it in the right boxes. it's not only fun, but it helps in paying attention to detail. please let me know where I can find some really good ones.
it's really helpful for beginners, too.

and I absolutely love your picture, by the way! it's so lively and colorful! I would call it "eye candy" ha ha
