1) As someone who doesn't rewrite his older fics released on FIMFiction.net to bring them up to his current writing skill: He doesn't because his pictures are finished pieces of work that reflect his practice and skill level with the new style at the time he was drawing them, because he wants to document how the style evolves over time and because it would be too much to go back and "fix" every single one of them anyway.





2) Because it's his art and his decision what jokes he makes in his comics, not yours or anyones.





3) You are not in a position to make any calls of his art. He provides you with free entertainment without asking for anything in return other than not bitching and complaining around in the comments under his uploads.

Be patient and see how his new style evolves, if you still don't like it, either move on or commission him to make an art piece for you that looks exactly the way you want it to look like.
