Well I guess you picked the right one because I'd 
have never picked the TSK one on my own ^_^.  
I've ordered some of the illustration artbooks (I 
only have some scans from the first two) and I 
can't wait.  After I finish my current commission 
I'm going to work on one that's all 
transparencies (Sakura, sitting on a giant 
transparent white flower in a matching dress 
hugging a bouquet of smaller flowers).  I think 
that one just might kill me, but if it doesn't, 
I'm going to need those artbooks for more 
challenges... ugh, I'm such a nutcase.
