This was my very first custom from about 4 years ago and my first attempt at making a base too.
i'm a massive fan of the juggernaut and when i saw the original figure i thought that'll be awesome with some work. so i put some thor (marvel legends i think) arms on him. bulked him out with some putty as well as adding some extra detail like the bands on his arms, battle damage on the armor etc then i finished with a paint job trying to keep his signiture reddy/bronze colour and he was then complete.
the base was made from loads of random fodder pieces and clay
hope you like
