I does not seem to be bad but there is only one pictue where you may see the crane; from mill you see allmost nothing (that house could also be a normal house for example). Please add more picture and/or a download like (at least nbt Data).
You should maybe also add a description how this crane should work - because I dont't see the steampunk mechanik in it; its a normal crane to me.

Hey nice Build! How would you feel about making a steampunk area in our server? I like your style and i think you would make a good adition to our team!
