I don't know if it's another artist. A name sometimes isn't enough. In this case I'm fairly sure it's the artist. Several points I'm going to make here:
1) Some artists' styles do not translate well or at all on Pony or other checkpoints;
2) Considering what this artist draws do you think I can post "accurate examples" of his work here?
3) I train models (which costs money) and upload them here and people can get them for free. I don't even use the "Early Access" ridiculous buzz farming that some people here do (like asking for 50,000 buzz for a concept that is already inside the checkpoint). Because I think of the community first. How does said community respond to that? By laughing and crying at the images and models I upload.
4) Put out a bounty for the artist, maybe someone else can make you a better model

@ninjahatoori8 It's all good, no need to apologize. At least you are providing feedback and criticism unlike other lovely people who think they are on Facebook, reacting with a laughing or crying emoji to something that's neither sad, nor funny. I'd reward their intelligence with buzz if I knew their names, but alas...

I'm also seeing what you've found out with this model, though. It's hard to train a model on the images of this artist in particular, because most of his work is in a manga/comic format, so the model (while training) has problem focusing, because there is way too much variety in each image. I might try with a tiny dataset, but usually those are not great.
