I wouldn't say Bowen sculpts have always been great because they haven't. I've seen Bowen's earlier pieces and they just don't look as good to what he's putting out now. Of course fans will like the style of the early stuff as well as liking it out of nostalgia but clearly the later stuff is real good. I often wonder why Bowen does revists of characters already done in the past. If the pieces where that good why go back and improve the character. Plus with so many characters being done by Bowen they have to use outside sculptors who are not that great. Overall both companies are real good and I collect both I just wish Sideshow had variety.
Imo the older sculpts are great (iron man, punisher, phoenix, silver surfer, logan, etc). There's a lot mini busts in the past, and even though im not a fan of the scale, the sculpts are impressive.
If you dont think so that's totally fine. I just disagree that Sideshow is the reason for the improvement. Any company and artist will improve as time goes on. That's the way it works, not because one company is putting out other marvel products. Besides, bowen and sideshow are not even competitors. Sideshow sells 1/4 scale and dioramas, bowen does busts and 1/7 scale.
When he revisits a previously done character it is usually to improve on the pose, not the sculpt. He did the first surfer as a museum pose. this new surfer we got is an action pose. etc....
