Just some praise here – I LOVE the elements you guys have made.

One good starting point is design inspiration sites like:
Let me know if this helps, and feel free to share your creations here for feedback so we can speed up that improvement process! 
Have you checked out Youtube videos and courses on UI/UX design?

And if you want to learn some actual standards (padding, visual design of elements, color theory etc) check this guy’s courses out: https://hype4.academy/
Hope that helps!
