Sketchbook stuff²

I haven't drawn anything since last Wednesday and I felt very lazy because of that...until now:

 Still I'm feeling like I haven't had a good idea in ages...

I actually wanted to print a card game someday, but I just can't come up with any concept for the pictures on the cards.
I'd also like to redraw my misanthropic cactus and make a screen printed postcard of that. 
And then there's this half-baked idea for another artbook about blood and its usage throughout the hostory of mankind.
Also Paul and I are planning a new cooperation!
So actually there's a lot to do, but I'm not really doing anything, because I'm still tired from last week...
