Okay guys.

Theres a caviat about hitlers paintings that many are missing and that was WW1.
A lot of the hitler paintings you see that look really boring and bland are pre-ww1, during the war he continued to paint and actually got better at his artwork, art historians have pointed out that if he had enrolled again he would have been accepted as his artwork during the war period was more expressive, and less bland.
However hitler got into politics. If you look at his later artworks (which there is very few because these paintings were taken by the US government and are just locked up in a vault) youll see theyre more loosey goosey and less like architectural concepts. He typically painted and sketched his dog in later life and even did quite a few nudes which are also locked up.

I think important context is missing from these types of convos. Hitlers artwork improved beyond his initial denial from art school and most of his artwork is destroyed / in private/government pocession so its difficult to get a clear picture.
