Given the team, I find it quite unimaginative and generic. I find it to be unoriginal and bland. While sure, it looks official, I don't see the point in making tiles like this. The reason Nintendo make theirs quite rough and lack smoothness in Black & White is because they have not mastered the creation of textures through 3D for their environments. So consider Pokemon Black and White the Pokemon Red and Blue of 3D Pokemon graphics. I see little point in emulating crude 3D textures through pixel art. I'm sure you personally enjoy the style, but I find it some what senseless to recreate something which could be improved graphically through the medium you guys use.
I notice how even the screen size is the exact same as Nintendo's DS size. Try another aspect ratio. I know this is a remake, but sincerely, I feel it should be a remake in your own style, the style the team create.
I can understand why you may want to look official, but there's a difference between copying the official games, and making something official looking. The latter is what you should strive for, but this quite heavily based on the BW games, and it's already a remake, so with those two things teamed together, I find this screenshot to be weak.
Forgive me if you feel the comment is harsh, I hope you and your team can take it and understand where I'm coming from.
