as an actual asset creator i can tell you that this kind of model would be fine for a mod but not a full title.
the reason is the topology.
that kind of edgeflow messes with hitbox calculation and you would have to create a separate phys model for the calculation.
you should never model with tris as the game engine will always draw/convert the quads to tris for you.
with that being said, it looks pretty good shape wise.
if you can fix the topo it would be a game worthy mesh.
