I'd like to start off by saying that the plush looks adorable, and i love the way the mane and tail are shaped. However, there are a few things I'd like to note for improvement.
The head shape is good, however I suggest perhaps enlargening it just a tiny bit, seeing as it would make it more show accurate. I would also give a more pronounced snout or nose.
Now for the body...the front legs are fine. But the back legs need to curve back more, and perhaps you should thin them down a bit. Sinc e there is also a indent and point in the show, to make it more accurate, I would enunciate that a little more.
The mane and tail is very cute and well made, However,the iron on eye is twisted down by a few degrees, so for future plushies, I would straighten them out a bit more.
Overall, you did a very nice job, those are just a few pointers I have for your plushies.
Very cute! Keep up the work~
