I like the way you emulated the forge with these metallic thumps!
The track overall seems to be lacking development and melody impact. There is nuance, but tuba and horn definitely aren't enough to fill the space. Your melody is clear, but isn't memorable due to its length and verbosity, and lacks a clear direction. My advice is that you use of repetition, have a simple motif you build your song on and introduce variations for development.
