Yeah, I've noticed that myself. I was browsing through your gallery, and you've made a lot of really interesting plushies. I got to say, I do like the style your going for with your designs. It works quite well, particularly with anime characters. That's another thing I've noticed with other artists, they don't usually make to many humanoid based plushies. Most of the time it's animal related characters, like the ponies from MLP, or the dragons from Spyro. It's probably because humanoid characters usually look a bit off as plushies, whereas non-humans characters can generally retain their ordinarily shape.
It’s great that you feel that way about your work. Most artists on this site tend to usually just make plushies from the more recognizable characters. That’s actually how I ended up discovering your DA account. I was just looking up fanart of Melody, and by chance, I found a really adorable plushie of her. Melody is one of many characters I really like, but would never get any merchandise made of them because of how obscure they are.
