First off, thank you so much for giving such an in-depth critique! Your explanations were crystal-clear and devoid of any jargon, which from a beginner's perspective is super appreciated.

Anyways, I tried to give the room another crack with your advice in mind.
I feel like the biggest difficulty I'm running into now is balancing my global light source (which, in theory is supposed to be in the upper-left) and local one (the window), leaving the panel's/television's shadows in particular very jarring. I've experimented a lot with those and not really gotten anything satisfying so far. I'm quite inexperienced so if this is more of an art fundamentals thing and less pixel-specific don't be afraid to tell me! I don't want to be wasting anyone's time demanding them to instruct me on basic artistic principles.



I think I understand the reflection business, minus the television, but if they're super off and i'm just unaware here's a sprite of the bed for ease of editing.


Thanks again!
