Brilliant, it's always nice to see things like this being made. The two shown there are nicely done I would just have to say one thing though and believe me I've had this problem many many times, they don't seem to be in proportion with each other.
Where these made close to each other? I tend to start straying away from the original proportions over time and move onto something else, usually now I keep a sort of Master Copu for reference next to any new ones I make now.
Keep going I'd love to see more of these.
