Looking good, very nice for first vector, even if you still struggle with the mighty foe known as eyes... ^^I don't want to sound like an expert since I've recently started myself, but I think some critique will be helpful. Writing out everything I've noticed would be too boring so I've made this , circled out some of the more noticeable slips. My advice for you - don't be afraid to experiment with layering to make things look good, especially with things like tail and mane. correct layering of the following colours really makes things easier and requires less attention. Also I think some unnecessary anchors sneaked in when you were editing, you gotta keep your eyes open for that. There are also some corners that could use smoothing out, but you're doing really well for a first attempt. Keep it up!
