What a perfect style! Very unique, refreshing and good to look at! I like the Professor's eyes the most! Incredible job on the sky and highlights! It is nice to see some different Layton fan art. I like the nod to Hershel's love of tea and the cow festival in Dropstone.
If you do not mind me saying so, it reminds me of that classic cartoon 'The Snowman'; I know most artists do not like their art to be compared to a popular art style and prefer for it to be described in words, so I apologise if this sounds rude. I mainly love the flexibility displayed in the characters, the more realistic touches to their faces and the charm of the game lying within the whole piece. I am looking forward to browsing your other artwork.
