I really enjoy this piece of art. The lines seem a bit shaky, and it's lacking facial features. I love it's cutie mark, quite original in my opinion. The wings seem a bit disproportionate, but I enjoy it's overall fur and hair color. I'm slightly confused as to why you outlined the lighter blue color with black on it's tail, but not on it's mane. An overall good piece, albeit a few mistakes. As earlier stated, it's lacking facial features, and I think the mouth has a lot of unused potential. I'm looking forward to seeing more art from you in the future, best of luck!
This is a wonderful line art drawing! You have the shape down perfectly. The lines could be a bit straighter, and the character could use a bit more facial features and details. (such as hooves, feathers on the wings etc) The more you practice the better you will get!
Your choice of coloring is PERFECT! You have a real knack for choosing colors that are pleasing to the eye. The way the mane and tail were drawn is also very well done. I can just see that mane waving in the wind!
