#1 was well done, but I like sigs to have more colors. My vote goes to #2.

1 is really good, but samurai panda is too adorable, thus it gets my vote. I've seen the wallpaper of that panda a ton of times on /wg/ and I've always liked it, it's nice to see a sig of it. Colors match, background and all that stuff is good, etc. etc.

I actually like the black line in that first tag. It added some sort of uniqueness to the signature and is not of the norm. So for that, big points for trying out something new. Plus I can see why the artist did it, and it's pretty clever. xD So good job on that. Great signature and I love the work of brushes here.

Well done to Mitsuki for winning SOTW again! ^^
