If a piece is packed well and correctly big or small doesn't matter. Really your chances of either getting damaged are about the same from my experience.
Really any piece can have attention drawn to it if placed correctly, put a 1/40 on a table in the middle of the room and people will certainly see it. Put it on a shelf with 20 other models though and it's white noise except to the discerning collector who shares your interest.
Personally I like larger pieces because I can see them across a room even. The details are clearer for me and much easier than trying to take a magnifying glass to it. An example is these two Krentz Rexes :
1/20 and 1/40, both have fairly detailed paint schemes..but which one can you see better ? My best example is the eyes. Those of you with the SS Rex know that it has really nice eyes that feel alive. While at 1/40 it's almost impossible to get that. the eyes are mere pinpricks. So a scale like 1/40 is fine for observing the overall animal but if you want to really see the detail 1/20 and 1/15 are great..of course 1/1 is the ultimate..lol
On the topic of the Stegosaurus, I was assisting Jorge last night in figuring out the scale. We think that if it was 21' it's a 1/8 or 1/9 if 30' it might be 1/10 so she is a big girl for sure.
Jorge said he wants to do a similar scaled Torvosaurus to go along with it. I'm quite excited but that will certainly be a challenge to display.
In other news he is still working on some statue concepts but he has no idea where Sideshow is with the line . He did say he would inquire and try to get an answer for us. He does hope to do his own line of resin kits so if you really loved his work so far it's quite likely you won't be out of options.
