I think digitigrade version looks a bit more fun. Maybe it's about the feet on the left version being a bit flat and more like they are bended metal sheets, rather than joints or something. That's how I see it anyway. Also I'd say I just like the version on the right more overall. Don't know if it's just me, but it seems like you gave it a bit more thiccness, like the shoulders are a bit rounder and wider, the neck looks thicker, thighs too. With all that plus the legs being animalistic, the right one looks more menacing to me. Not and expert though, so just stating my opinion
