Hi, sorry for the late reply!
Thank you for the advice! I'll try to change my pallet.

Very nice first entry with vibrant colors, I especially like those jars and jewels! But here's my suggestion... there are way too many colors for this type of items set and the resolution (Image specs tool says 252) and some of them do not serve any purpose. As an example, these 3 blues are almost identical:

#1f70e7

#2070e7

#2071e8

So you should either use the existing palette or create your own, but IMHO for the image like this you shouldn't need more than, say, 64 colors reused for all the items.
