I had a little trouble deciding what colors I should use so if you have any suggestions please let me know!
[UPDATE]: I made some changes to the UI based on some suggestions. I changed the color of the shop and missions and I tried to make the mini-games icon look a little smoother. I decided to keep the words to fit the “Roblox game” theme.
This is one of the best UI designs I have ever seen. I love how you put great detail in your work. You should do this as a job. I’m sure somone will want to hire you.
They look great and impressive.
However, If you are trying to follow the reference picture then I suggest you remove the text. That is if you want to remove it. The icons are pixelated especially the Robux Shop. The Mini-Game is bent and looks kind of weird since controllers are usually non-bendable. Try adding different colors to it. Change the Shop into Green maybe since it is associated with money and change the sword to blue. Yellow is already used for the Star Pass.
Anyways, do what you gotta do. It looks great. Good Job!
