settings seemed fine.. if you use Auto (without flash) then its okay and if you use the M,P,A,S mode then use A mode and keep the aperture the highest (smallest f-number)
No need for RAW my brother. JPEG does the job good enough, All the picture you see here were taken in JPEG. I use RAW for serious paid professional shoots. Use JPEG 
I would say that you need to process them properly via a good software like Adobe Lightroom. I highly suggest using that software only and watching some tutorials via YouTube. That would help you learn the basic and polish your skills even more.
