Any advice for photography lights?

Usually when I take a photo of a traditional painting, it’s hit-or-miss whether it will look good or not.

Good. . . .

. . . and not-so-good.

That’s not very satisfying.

There is nothing wrong with my camera (Canon PowerShot SX530 HS), so the next suspect is lighting.  Of course, natural sunlight is best, but there’s no guarantee that the sun will shine when you need to take a picture.  The next best thing is using studio lights.

I’ve been doing some research and found a couple that might work.  I’m a hobbyist, not a pro.  A beginner set is fine.  I want to experiment with studio photography and use it for my hobby as well, so if it has a few different lighting options, is easy to set up, and looks (relatively) good when photographed, then I’ll be satisfied.

This one by LimoStudio might work (link to Amazon). It has good reviews, is less expensive than some others that I’ve looked at, and comes with a backdrop set (for studio photography).  There’s other options too, of course.

I know some of you are way more experienced with photography than I am, so what’s your advice?  How do you get nice lighting in your work?  I’d appreciate any pointers you can give me! (>.<)
