Artist Cathrel made some pretty amazing images of these four wonderful characters of the Heroes of Olympus series. But not only did he create a set of them once, he did it twice!  So, he created a meme to compare between the two sets.  One was done in 2010 with pen and tool, and the other in 2012 with a tablet.

What do you think?  I actually think I prefer the 2010 versions of them, but they are still both great versions of the characters.
