NDA Art Critique Message Boards

Okay, I'm not looking for tutorials. But does anyone know of any photoshop excercises they find useful in improving their skills?
I'm looking to improve my photoshop abilities because I want my ps drawing to have the same quality that they do when i draw by hand.

Thanks for your time ^-^

I already has the same qualities, except better. I use GIMP, but PS is much better in ways, I still need to figure a few things out. Do you have a tablet?

Yup, I have a tablet ^-^ I'm just trying to see if anyone has like "I try drawing 10 perfect circles in ps everyday" or something like that but more useful

Try making quick sketches in PS. Just leave PS open while you're surfing the internet and then doodle when a page is loading. That's what I do.

Making clean digital lineart (like here: http://kuridoki.deviantart.com/art/Tabl ... l-28278420 ) seems to be good practice too.

Thanks a ton (:
