I'm no pipe carver, and some on this thread are, so take me with a grain or two of salt, but I'm pretty impressed with your first effort, nice grain, plateau and all. I'd vote for leaving the stem straight since the bowl is so very oval and plump. I think a bent stem would round it all off too much, but some of these guys are accomplished carvers, so again, take it for what it's worth. I'd be exceedingly proud of myself if I'd done that pipe, and would be insufferable for about a week before I got off my high horse. Congrats.
