Hmm... if you'd like some feedback: you should make at least a specular map for it. There's no way rusty metal and paint can look even remotely realistic without one. Don't be scared, there's nothing hard about making a specular map: Its simply a greyscale map (okay there
are colored specular maps but a greyscale map would be sufficient here) - parts that should be shiny are bright, parts that shouldn't be are dark. In simple cases like with this door it can easily be done by applying some Photoshop functions like desaturate and curves or brightness/contrast to your diffuse.
Normal map is a bit trickier but if you have photoshop you can use for example the NDo plugin to get decent results.
In general I'd erase the door handle and chain from the texture and model those as actual meshes. Also you have parts of wall and doorframe on your door, those should be cropped.
