Not like this one is not good, it is just too normal and average even inside the genre itself, half the art portal is already erotic art and it is way more explicit, diverse and even if it sounds like a redundancy it is also more erotic than this one.
So really if i get a choice between more of the same and something different i will go with the second option.
Not to discourage you, but if you want to keep this style and take it toward this genre, you will have to make it more wild and daring, and more importantly more polished, look at the nipples of the purple haired girl they can barely be seen, and the connection between her neck and her head are awkward, i could go on with this but you get the idea, keep working on it.
