Ok this one here is amazing and it just really has all the details you would want in a comic panel, but I am a bit sad it isn't a full comic and you only gave us part of the comic. I understand why you don't want to share the entire comic with those on the site, because it can get you more hits and traffic to your own site, but it would always be great to submit the full thing here as well at a later date? I think that would help get you more fans and the traffic can come from that. Just an idea for you to think over. Now the art here itself it very good and the shaing is on the level of an actual comic, like something from "DARK HORSE" or "DC" and I do enjoy what you have going on here in terms of the facial detailing in expressions and the overall body language you're drawn here to match her words. Now the main star of this is in the title, the very "BELLY BUTTON" and I do like that. I think it is very detailed in a good way that isn't a sole focus, but you know that is what is to be looked at. I like the way her breasts are more of where your eye goes as they are beautifully round and expressive with the nipples being so pointy and portruding outward in an inviting and sexy way. I think the juice and body fluids and shines here are also well done and it makes you think she is really enjoying herself, which is always something you want to see in this kind of art. I think you have a real talent and hope to see the rest of this comic soon and not just the one panel, but as the panel itself it is good and detailed and your shading as always is spot on and well done. I think you bring good stuff to the portal so keep it up.
~~THINGS TO IMPROVE ON~~
As stated above, just show the full comic and not just a piece, because I would love to see the entire thing.
