I know I messed up on the right leg a bit.
Add textures to the wall, because it’s currently looking plain.
Overall the gfx is pretty nice, I’d add sunrays and change the window to an actual glass texture and like @RontheDragon204 said, add textures to the wall, cus’ theres nothing much to look at. Some pbr textures and better lighting will improve the quality of the gfx dramatically.
The lighting is slightly appealing you could consider giving the building small extra details perhaps some wall elements features and include additional objects if ever needed.
Overall, from my point of view, there seems to be noise underneath the window part and door border frame it could be caused using a low sample you could try adding some background in the scene e.g. players walking or interacting with each other.
The use of light is natural and you could always experiment with other use of colors and probably incorporating some materials within the build, or placing some details as it does lack other features that could be improved. It’s a basic design you could always add useful objects if you plan on improving it later down the line.
I’m honestly not amazed by GFX and roblox render. You can see alot of games in ROBLOX overused this and its a matter of who makes a better design and if you are going to GFX you gotta level up, not trying to be rude but it does need a little work! Keep it up <3
Try using different pants on the ROBLOX avatar because currently they are really blurry/pixelated and not well made.
