@clayathan I am generally less critical of visuals since I tend to look more superficially at things like this. I spend a lot of time in my regular job scrutinizing things for inconsistencies and discrepancies, from photos to written documents, so when I look at art or play games, I tend to try to turn that off and not look too hard.
With that said, while I agree with the previous comments that the bedroom might be a bit large by normal conventions, I have definitely see larger in real life and it doesn't strike me as being an issue. In fact, my wife and I owned a house where the master bedroom was probably twice that size, easily, with unnecessarily high, vaulted ceilings. The master closet was almost as big as some bedrooms. I'm not sure why the builder made it that way, but we rather enjoyed it. We had an entire sitting area away from the bed. I was easily the size of two master bedrooms.
And we looked at another house fairly recently when we were buying again with a bedroom a little bigger than the one you made.
Which is why the size of the bedroom doesn't immediately strike me as being too big.
I can't zoom in, but something about the night stand looks odd. I can't tell whether it is supposed to have legs and the space underneath looks strange or if the front is solid and that space still looks a bit odd. Perhaps I just can't see it well.
But a more general comment, it looks like you might have made all the art yourself. In which case, very nice!
