A kinda oppai obssesed artists, there are buts here an there, but looks to be more fixated on the "frontal attack" more than the "derriere", not a bad strategy, and i like the perspective of some of the characters draw.
What feel odd, is the lack of "life" in the color palette, snd the "stiff" feeling the same use of color gave some of the pics*. i thinks if the coloring improves, the art does too.
*: 100% a personal opinion, some pics just didnt feel right for me, even if they were ecchi.
