What initially threw me about Moline's art is that the characters don't much resemble the characters I knew from the show. Jeanty's art isn't always spot-on either, but he manages to capture a lot of the essence of their facial features that make these characters familiar to me - the way a character would look over their shoulder, or sigh, or smile, or show fear, or show anger. These are all things I can conjure images of in my head, from the TV show. So I see the comic and see images of these characters that I know, and I see something familiar about them in the art - it's more than facial features, it's about their expressions, their emotion, their essences - and I connect again.
With Moline, I haven't been able to connect in the same way. But I do like Moline's art. It's very bold, and his inker is bold along with Moline's strong lines. It fits with the Fray world and the older Fray comics. His art is very modern/contemporary and I can tell that he has a strong image in his head of what's going to go on the page.
Given what little I know about comics, his strong artwork would be great for a strong hero feature where the characters and stories are all very bold and in an urban setting. So in my mind, his art fits with the Fray setting.
What would be even better, for me at least, is an artist who drew the characters more lifelike. Someone mentioned the 'cartoony' look of the comics. I've seen some comics that looked so real you could reach in and touch them. I'm sure that takes a lot more time and money to produce, though.
