Marin retro MTB looks disproportionate, is there a fix?

Bought this bike recently thinking it would turn into a great neo-retro MTB build, likely a commuter. Handles great and bunny hops were never easier, but the looks of it are throwing me off a bit. The stem is obviously too short, the stack of spacers too high and the seattube looks too long, but I can't have it any lower. What do you think could save my Marin?

Already done:

\* Seatpost replaced, the old was all scratched. Now I see the seatpost needs to be replaced again, as nooffset looks wrong.

\* Steering tube extended to make ahead compatible

\* Headset replaced black -> silver

\* New, wide handlebars from Ritchey, 78cm in width.

I love all the silver components though :)
