The idea of combining all the maps into one is a good concept but it doesn't execute very well. The features that you've taken from different maps where actually there for the purposes of that specific map. Mixing them with other map landmarks does not turn out well. I also think you should have put the Foundry tunnel to better use instead of just placing a lone sniper in the middle. Overall 3/5 due to the quality of the forge, not the concept or design.
