Fair enough. But it is better to explain to them what they are doing wrong and telling the OP what you expect from them, which I think is exactly they are looking for when they said ‘We’d love to hear what the community thinks’. So instead of outright telling them that the textures/materials are not good, tell them what you expected and why you find it lacking. will help the OP to improve their offering and in turn will help the community as well.
