It is good to have an option.
I think the fat window outlines on the painted shell shown, make the thing look heavy and clumsy. It could look better with different paint. There looks to be so much surface that you can bring out the Touring Car designs
I don't admire many of these alien style designs. This certainly looks bulky.
The kit shell is interesting, and at least refreshing, I just don't think it was finished off. The ideas are there but some of the elements just make it clumsy. It would great if they could afford a top industrial designer to refine the current SX shell.
It looks like the Tamiya 511 shell could work on the SX. At least that has design balance, and would be well made.
