Would like some feedback on these UIs, since I always ask myself if should I tweak something, and I don’t know what the ‘something’ is.

Some pictures:
I’ve moved this to Cool Creations since you’re looking for general feedback.
Looks pretty nice! Well done! For the “Quick Ads” button in the second picture, perhaps change the color from green text to how it is in the second picture. Looks like a great UI overall! Have a good one! 
On the right side, I’d change the background color to a little lighter color to appeal more. Darker colors and lighter colors for simulator games don’t combine well.
Thats just my opinion, oh well.
Gradient to the UI’s looks preferably nice. For quick ads button, I suggest changing the font to a more bold font since it would make it easier for people to read the text. Although, for what appears to be the coins or credits UI, the GUI design looks very good.
