This artist goes from the delicacy and extreme erotism with his micro bikinis and lewd lingerie with minimal backgrounds to the oldest (?) pics done by his hand where he used to work the same or more amount on the background rather than the character.
it is nothing bad, some of those are really good Bgs, and looks like he reversed from his old pics to make that, but returning way better with more style and better art as the first pics depict.
Great, it is wise to make mistakes and evolve from those.
