It reminds me of Fantastic Frontier (great game, love the art style). If that was would you were going for, you nailed it.
It looks great! A lot of detail. It looks from this point of view though that the two closest walls are empty.
Looks great, The only thing I can suggest is adding more variation in the positions of hte books
That looks awesome! 
Perhaps add a bit more of the stone sticking out on the two walls closest to the camera, as they are in the ones facing the camera.
Looks great,the art style is really good and there’s alot of detail,you could add a little more stone on the walls closest to the camera tho
Great work @CloneJester! The potion room you’ve built looks fantastic. I particularly like the warm lighting you’ve used. It really helps to transform the room into a warm and homely environment. The cauldron in the corner is also a nice addition.
Clipping Effect
In terms of possible improvements, I noticed a couple of areas in the environment where parts appear to slightly clip through one another. The first instance of this clipping effect occurs on the lowest shelf to the right of the bookcase, in which instance the shelf clips through the bookcase. The other instance occurs on the stairs, which is more noticeable but may be intentional.
As these seem to be the only areas where this clipping effect occurs, I think fixing or hiding the effect would help to keep the environment consistent, adding even more polish in the process.
Floating Potion Bottle
I also noticed that unlike the other potion bottles in the room, the potion bottle in the top-right of the screenshot is floating above its shelf. I think moving it down so that it rests on the shelf like the other bottles would help to keep the environment consistent too, although with a few particle effects you might be able make the bottle appear as though it’s floating around the room with a life of its own!
This is a beautiful scene dude, looks like classical Roblox! As for feedback, I’d make the size of the ladder steps smaller so the faces away from the ladder’s beams aren’t matching the face’s relative position; pictures included below. Honestly though, that’s a stylistic preference and I think your ladder looks good regardless. Love the scene, and keep up the awesome work dude!
Not bad at from my opion. But you should add more detail in some of the walls.
Nice, I’ve always loved cozy rooms full of detail. Great job! I’d also suggest fixing the potion on the top right, it appears that it’s floating.
It is looking pretty nice. Only critiques would be that the walls are very empty (the walls adjacent to where the picture was taken from). Also, the ladder lacks a lot of detail, an definitely could be improved. Overall- looks great!
Really great build you’ve got going on, BUT I can tell youre kinda going for like a messy/abandoned feeling from the scattered papers on the bottom of the stairs, so what if you added some cobwebs or something along those lines in the corners? And a spilled potion here and there would really do wonders to the vibe and feeling of this build. So far so good, though!
