Worse, it looks like an attempt to copy TF2 art design by someone who thinks it really is 'anything goes'.
Whatever flaws TF2 might have, the art design is superb from a functionality perspective. Each character is instantly recognisable, and from the very 1st game you have zero difficulty mixing up opponents' classes. All of them are distinctive from the far side of the map, and (more importantly) they are all distinctive even when only a small fraction of the model is visible (you can instantly recognise each class, even if there's only a limb or the top half of their head sticking out of cover).
What's more, the design is excellent at flagging what each class does. If you've never played the game before, the visuals make it very easy to spot where the 'danger zone' is for each enemy. E.g. the soldier's eyes and posture (looking into the distance) make it instinctive to realise that he can be dangerous from long-distance, whereas the squat posture from the demo gives you a sense of safety at distance and a sense of danger when the demo gets close. You're never stuck guessing which classes will have high HP and which will be squishy, the difference between L1, 2 and 3 sentries are immediately obvious at range....from a pure functionality perspective, the design is great.
