Get a fav icon firstly, as you're using the vb default one at the moment.
I'm not a big fan of the skin but that's just personal preference
I think the place needs a little custom touch, up-grade to 4.2.0 and get the Activity Stream
I think this could add a little nice touch to the forum

Another maybe personal thing for me would be I'd never let members have Huge picture/moving picture signatures.
This could make the front door of the forum where guests enter look nice too
