Ah, a catgirl and tentacles... Classy!
If there is one type of girl I love, that would be catgirls. How can you not love catgirls? They're cute, elegant and they give that huggable and moe feeling one can not just love. And it appears that tentacles think so, too.
What I like the most about this illustration is the color palette and, by extension, the cum, sweat and movement effects. The coloring is wonderful, just like in Bigdeadalive previous works. I like Nathy's hair color and ears, and also the different shades of green used for the tentacle monster. Speaking of shades, I like how the diverse liquids look vastly different from one another. The cum looks white, while Nathy's sweat and juices take a lighter and transparent scheme. Now that's a good piece of work!
The lights and shadows are also wonderful: I like how there's a balance in both of them; Nathy is a delight to look at, thanks for the lightning and brighter coloring, while the tentacles have a darker tone, which helps in giving them a more unreal feeling.
The background also helps; the main focus of the picture, Nathy and the tentacles, go uninterrupted, so there's nothing to distract the subject of the illustration.
I love how this one turned out. Everything on it is a delight to see. I dare to say that Bigdeadalive has given us another hot and great piece of art.
