I made a miniature salmon and veg platter recently.
I really like to combine lots of different techniques into one miniature. It makes it more interesting to make from my point of view, but I think it also makes it more interesting to look at and notice all the different things you can do with fimo.
There are slightly complicated canes in the tomatoes and cucumber and a simple one in the carrots (look closely and you'll notice they're paler through the centre). The salmon fillets mean making a cane that isn't the standard circular shape, and the asparagus make good use of gradual colour blending.
I also enjoyed messing around arranging everything on the plate. All in all, this was a very fun miniature to make.
