Looking at it again, I do think the painting is just amazing. Out of interest, have you any idea how long it took you to paint this? I don't have the skill to do anything like this but, even if I did, I don't have the eyesight anyway.
As an aside, I used to be quite interested in model railways. I collected models in scale 4mm to the foot. Quite a few well-known modellers started in that scale but have had to change to scale 7mm to the foot as they got older because their eyesight deteriorated and they could no longer manage in the smaller scale.
