I see you've already learned the art of the tripod and slow shutter for deep depth of field! This is a good DPC shot - clean, simple, meets the challenge well. I do like how the editing emphasizes the bit of shadow - that gives it a bit more "foundation" than just purely floating on a white background.
This is a cool pick. I like the composition and the way the red pops but it doesn't take over the pic. I think it would have an even stronger effect if it didn't have shadows. More even lighting from both sides might change that.
