I love the base figure (energon omega) so I decided not to go out of my way and add extra parts, since it has a very decent proportion. Instead I gave it paint job that emphasized Omega's core colors - yellow, red, and grey. I did a number of washes, dry brushes and layers in order to give it a slightly more "worn " look than the average figure, but not so overkill that all it has are war-torn scars ,etc. I still wanted it to look somewhat cartoony.
I did modify the head so it had a more " rounded" look to it and wanted to maintain the "headmaster " aspect. Also painted the headmaster to be a mini-supreme (or a personal pan).
I've also decided to put it on the ' bay so you can check it out if you want to see more pics.

Thanks for checking it out!
