Inktober Day 21 word is TREASURE and 21 will be a busy day to me so before went to sleep here is my contribution for the challenge.
When we think in treasure we think also in kings, castles and palaces.
I will participate with an old work made in my mobile phone with Sony Sketch App for Android, because is an old work and not do it for Inktober 21 I don't have the full work progress.
Pena Palace, Sintra, Portugal
Here is some images from Sony Sketch layers for proof of work.
Because Pena Palace is a World Monument, an icon of Portugal monuments and a real Portuguese Treasure, I will leave a photo and a link to you know more about Pena Palace.
