Uh oh, as expected, choice of art overhaul direction looks to be a divisive topic!
G's work is the most polished and finished looking at the moment, which I think a lot of people are consciously or subconsciously latching onto. It seems like it would be an OK match for the tone of AVWW, based on what we've seen here. It does feel a little bit conventional, which is troubling given that, to me, the tone of AVWW is more "idiosyncratic and sophisticated intelligence" rather than "your normal action game".
K's looks promising, though I worry that the style is a bit too exaggerated for the tone of the game. I worry it will overemphasize the SNES/Comic vibe. While AVWW clearly draws inspiration from SNES and 16 bit era games, I feel like it is still primarily a sophisticated, modern game made in the age of procedural generation and "naturalist" SF (the BSG decade, if you will). I think the art should reflect that.
H's work is clearly still rough, and as such I don't want to say much about it. If their sprite artist can make things look good in motion, then I think their style has great potential to capture the sophisticated, modern tone that I think best suits AVWW. But the fact that the composite concept piece looks so disjointed is a little worrying to me. That said, I often see artists trained in 3D work doing concept stuff, and it shows - they are simply not specialists in drawing and color design. What really matters is what the sprite artist does with the concept pieces. EDIT: I adore their concept for the sniper balloon. The drawing is a bit crude, but it's super weird and cool as an idea. It's one of the reasons I'm so intent on waiting to see their finished work; if they can realize polished versions of that concept and the character art they've shown, I think they are by far the best match for AVWW's unique style.
Can anyone from Arcen clarify which of these studios is doing the sprites and which is doing the articulated mesh style? I assume at this point G and K are the sprite shops? If so, H's finished work could look very different indeed.
