Blocks are great hun, actually. What happens with blocks...it's like your brain downloading a shitload of information... meanwhile putting the entire program on hold. Once the updates are completed, aka the art block is over, your program now has a shitload of awesome new features...aka... you're a better artist than before. You'll do SOMETHING better than you did before the art block. It never fails. Other artists have noticed this as well.

The worst thing you can do is actually concern yourself over the fact that you have a block. Seriously, it's no biggie (unless you have commissions). Just go with the flow. The block will be over when it's over and then you'll have a newfound passion for drawing again. :D Worrying yourself over it will make the block last longer. Just give your artistic self a break for a bit. :)
