The first one is better, but it depends on what type of game this is. The good thing about the second one is that it’s colorful but too much. Nice job on these loading screens!
Number one gives off the impression that you’re serious about the game.
If I saw the second one implemented and my friends & I played, I would assume I’m playing a botted game and would’ve left. I’m just a modern guy, and the second GUI gives off cartoonish/troll vibes.
The second probably appeals more to kids if that’s the age demographic of your game. Maybe tone down the saturation of the second one and tilt the gradient a bit?
