Good Day Drunken Fools!

I was sketching yesterday, under the heat, and ended up revamping Spike a little. I really like the end result and I feel my art is really evolving since I started to draw in 2008.
Now, the dilemma, current storyline:

The Fools are now a Long Form Comic and the current story may end up having 45-50 pages. My first feeling is to wait until the end of the story before applying the new design. Well, that is, IF Spike returns under his human form, of course ;)

What do you think? In the past, it was easy to switch design as I was improving my art, I was doing short gags or stories.
Since I am planning a book for early 2011 and The current story will be the main story of the book, I still feel I shouldn’t change the style/design in the middle of it.

What do you think? What should I do?

Oh and… what do you think of the new design? lol

Spike's new design

Cheers!
