Again, (I commented on issue 2 before this one) it's addictively cute.
And considering it's your first sprite comic, I'm going to give you my blessings on it. You've avoided some major pitfalls. First of all, you're playing with your own facial expressions, two, it's not the usual megaman/dragonball/naruto/megaman crap that I've seen get churned out of the spritecomic world for the past several years.
