Looks great for a first attempt Ian,
All looks good, just looks like a little reelection of the tube showing through at the nib end but as the walls are quite thick on that pencil kit it doesn't detract from the quality of finish.
If you haven't already painted the tubes You will need to think about painting them when you do one with thinner walls as the tube might just show through.
Otherwise a spot on first attempt, wished mine was as good as that.
Keep it up and look forward to seeing a few more, don't leave it so long next time.
