Amazing! I love the photo study, and it's such a sweet idea too ^_^ Might just steal it
I did a similar thing for my late grandpa a few years ago, his wife (my grandma) died before I was born, but there was a really nice picture of her handing in the house, so I drew a portrait of her for him, it made him so happy As he sadly passed too, I think it will be good to do a portrait of them together, thank you for the idea ^_^
The rest of the stuff is awesome too, but this one just struck a chord with me <3
