Hi Chill, welcome and what a wonderful 1st as post and lamp, a great gift, as with Phil the base could have been different in colour and more detailed, but it's down to you, what you have to work with, you can only use what you have and the skills, judging this piece it is many, for some the twist would be hard, as for hollowed you've done well.
Are you totally new to turning or only just now taken to show your work, which is more than just great, keep them coming, hoping you'll not be too 'chilly'.. Cheers.
Happy turning. David
