Such a pretty pony! X3 The colors are beutifully put together how her eyes stand out with the green against the purple, black and grey make it simply, well, cute! the accesories he has, lithe sock, necklace, and coller, really bring in her personality.
The mane styles you chose for this pony make her look funky and creative. the cutie mrk makes herlook gothic, and the socks making her look spontaneous an dfun. I agree with this pony design and the whole picture itself. the pose, the colors palette, the design all jsut bond together to make this onderfull picture.
I enjoy the colors. They work well with each other and I'm glad she's a unicorn (cause most of your other ocs are pegasuses XD) I think her accessories are perfect for the theme! And her cutie mark is adorable!! Her eyes stand out, which I think is a nice feature, they dont blend in with her hair or fur. Im glad you picked the name hot topic, its a perfect match! also the blending you dis in her mane and tail is super adorable.I really love this design. Overall: I think you did a great job!! Love it bunches!!
