As already said grout lines, corners, dust sheets on work top, the socket is only half on the tiles in one pic, adhesive needs to be neater, i also noticed you started straight off the worktop with the tiles, you can run into trouble doing this as quite often worktops aren't level but i noticed there was a level in some pics so i asume you checked this before you started, looks like you started from the side wall i always start from the middle of the hood to make sure the corners are right. Doesn't look like you primed the walls first so i would read up on priming too
