There's a few things that look a little off that I can see, like her right foot, her right shoulder. The guys head is bothering me for some reason. I wouldn't personally flag it but everyone's got their own opinions.
Let's see, from what I can tell, other than the above...
-Pretty much everything about Makoto is weird-looking. -Meme is missing one leg and the leg she does have is angled/sized funny. -That's a pretty weird bike, no seat or anything. Erio's foot couldn't be blocking the entire seat at that angle. It seems the artist tried to use Erio's presence to be lazy and completely skip drawing certain things, which also goes hand-in-hand with the weird-looking angles and parts. Guy's left hand and handlebar goes where?
