Aahh, Art Nouveau, I remember doing a paper and work of Alphonse Mucha in my masters class. I went all the way and broke his 'all female' works by doing a design of Hades in that style. The teacher and students freaked out, but later commended me from breaking the "Mucha rules". Good times.
This is so cute and simple, the colors are very smooth to the eyes and even give a sense of tranquility. You have a very unique style. Very beautiful.
I'm a big fan of Alfons Mucha. His art work is very beautiful. The way you incorporated your character and style into Alfons' art nouveau style looks great. It's a cool idea for a dev ID. Keep up the lovely artwork.
