It looks okay if you’re a beginner. I recommend you use a website like Lightshot or Gyazo to take pictures on your computer so the quality is better. Now about the build, it doesn’t look very good. I recommend you not to use dark colors with those bricks for a building like that because it looks very bad. I recommend you use a different texture with a lighter color or a design/texture. Next up, the floor isn’t great. That carpet texture does not look good for something like that, I recommend you use a texture/decal for the floor from the library. The build also has some things that could be fixed such the picture in the image. Overall, the build isn’t the best but it is alright if you’re a beginner. I suggest you watch some tutorials on YouTube on the basic buildings and practice on your own to improve!
Try to develop more effort into replicating the original models into your own version way as a lot isn’t being shown in the image as it looks like a blue walls with some repetitive desk tables however that is something you’ll made as your starting out and learning
It’s an alright start building up your skills, even if you’re new to building, but there isn’t much to really give feedback on if your going for a sort of office build. I encourage you into making it fit the style so it doesn’t look like random models thrown in there. If your losing odds on what to add to your building use reference images to work on getting a better approach to whatever your trying to create the first image isn’t showing much as it’s just duplicated walls what seems to be repetitive (desks - tables).
Otherwise keep improving and figuring out ways to build of those free models.
It doesn’t look necessarily good or bad, for a beginner it looks ok. I suggest trying to build things from pictures or try to rebuild a roblox model. Remember, we all started somewhere.
For the first image, I don’t really like the brick material. If you’re gonna use textures, I suggest going with the ‘Smooth Plastic’ material and adding some textures. For the rest, it’s not bad for a Beginner. Good luck!
