I love Julian so much, though I can get where he's not for everyone.
Let's start it off: I love unicorns, and have since I was a kid. I have a unicorn collection, even... A collection that now contains a certain video game unicorn <3 So, even if I didn't like anything else about him, having a unicorn would always have been a goal for me.
Conveniently, I do like other things about him. I love the color blue, and I just find his design aesthetic, with the long, kind of wavy forelock draping into his face, his color scheme with its very cool and relaxed shades of blue, even the whole "eyes always shut" thing to give him a very peaceful, dreamy atmosphere. I just end up feeling very relaxed when I look at him. This is even increased by his house, which I adore and I've put a lot of work into trying to keep in the mood -- it's got this lovely celestial theme, and the music choice makes me think of lullabies, which works perfectly for that atmosphere I mentioned earlier.
Also, Smug is totally the best personality for a unicorn, and one of my favorite personalities to have around, so that's another point in his favor.
If I had to give one point against (besides his popularity and thus, his price tag -- I was lucky to get him in a giveaway, but I certainly could never afford it; still, I can't blame someone for having the same taste as me), I'd call it...Maybe the eyeshadow; I don't terribly like it, and think another color would be better. Oh, well.
