As far as aesthetics go, the only decent-looking Scum ship is the Y-Wing repaint (and original Firespray). All of the new ones, especially the Starviper, look like ass. But they have a lot of fun tricks and trappings that look to be interesting. Otherwise, I'd be right there with ya.
The star viper does indeed look, er, like a ship from a different franchise.
Frankly it looks like a Vorlon ship (sort of).
I have two, one I shall leave as is and one I shall "fix".
I think for starters I might fold the wings back. That would help.
The star viper is the first ship I've ordered just for the cards - I just can't get past how utterly stupid it looks and I can't imagine it ever seeing the table, at my house.
I might end up "fixing" both of mine with a hammer to save the storage space.
