30 second drawing (you can do different amounts of time and other things as well). It's an interesting activity in anatomy study. I got addicted XD
It's supposed to be training your eyes and hands or some mumbo jumbo. I think it probably helps. Obviously it's not going to be making any immediate drastic changes (as with everything in art)
I didn't bother scanning the sketches, but they're not detailed or anything (you only have 30 seconds to draw!!) Some poses are more difficult than others, but it's a fun little activity anyway.
I added new pictures there too. I'm not going to bother posting all of them here too 'cause I don't feel like bothering to upload (so lazy >_< ;; maybe later)
I've still got a bit of an art block, but I'm drawing through it like I always do. Instead of not being able to draw and having ideas, I feel like I can draw stuff, but the ideas have all just left me @_@; hmm. Dunno which is worse.. probably the former (more frustrating) There's always something to draw. You could redo an old picture or do a cliché subject (like zodiac something for example)
