I have been doing some items during this past week and ended up making some frames as well yesterday. Not sure how many more I'll do since I didn't intend to go beyond 8 or 10 at first, so we'll see...

What do you all think?

My only gripe is that I don't know if there's good cohesion between all of them. For some pieces I felt like they needed a darkest dark than others or an outline to work, and while I did set a maximum size, some ended up bigger than others.

Wonderful stuff!

Cohesion depends on a lot of factors... On this dark BG you probably all want them to be bright, now there are quite a few dark icons in there which don't match the others.

The angle is also important. Some icons are hovering in space (banana, sword), some icons are isometric (walkietalkie), some in perspective view (globe, perspective), some are planted on the floor (bird, stamp). Pick one and make them all in this way

And at last, the amount of details and different colors. The banana really stands out because it is only one colour and a strong silhouette. Giving all of them only 1 or 2 colors would make them more coherent, for example the wolf wig has 3 but could do with 2, same for the coins, the flowers, the chocolate...

Of course you don't have to do all of the above, but the more things you do similar, the more coherent the set becomes!
