New Animal Alphabet Print Design

The Animal Alphabet Series has proven to be among my most popular work since its release.  And I so proud to know that little ones around the world are growing up looking at my illustrations!  

But I've been tinkering around with the idea of releasing a new, redesigned version of the set.  Something a bit more dynamic and possibly in an easier-to-frame 5x7 size instead of the old 5x5 size.  

Here's one of the original illustrations:  

Jellyfish

And here is the tinkered with version I've been toying around with this morning:  

Jellyfish Variation

So tell me what you think!  Should I leave well enough alone or march ahead with a fresh new version?
