Have in mind that this is not the finished product, the Money category does not have a actual tab for them and there’s a high probability that some icons will be changed.
Style: Modern and a little cartoony, I suppose? Software: Only Roblox Studio and some icons from https://www.flicon.io/
Might create a system that automatically gives you the tools when you join your game, or the command bar via the developer console (Will most likely create a system)
Although I am not specialised in UI designing- I do some prototype designing. I agree with most of the statements by @0ffxInventor.
Indeed, whilst the project’s popularity may not matter, the quality of the project’s design would definitely be highly relevant to the UX. This may not exactly be a triple-A UI as you can only pick single guns from it without customisation and advanced systems such as tech trees, which means the UI is more decoratively high quality than generally at a triple-A standard.
Although I do not know much about colour rules, it is evident that the engagement and attractivity of this UI are not enough for the general public. With only blue, white and black as the primary component colours, it does not provide a futuristic vibe or a realistic military atmosphere. In reality, it’s just dark and under-decorated.
Indeed, the top-row buttons are too much to the left, misplaced under the logo, while there is not enough on the left. The infantry classification buttons are also somewhat confusing, placed after the weaponry selection. Thus we do not know whether it is a part of the weapon’s customisation or the actual gun type selection. There is some unnecessary space in the middle of the gun selection and the individual display box; it is pretty evident that it is much darker than the background colour and creates an unsmooth feeling.
Of course, @InsanityFE4R UI is certainly appreciatable and shows many skills, but again, it is not very kind to criticize others with notions that one does not even have.
