Yes, it works well.
There are several methods of getting a rounded cake top.
First, you can use an additional egg white, and beat the egg whites until they are stiff (not dry) before folding them into the batter. Then bake at least half of the batter in a loaf pan. The top should rise up, forming a dome much like a treasure chest.
Another method, also using a loaf pan. Bake two layers in loaf pans. This time let's assume they do NOT rise up into nice round tops, but bake flat. Turn the layers out of the pans, then, when the cakes are completely cool, use a serrated bread knife to shape one layer into a rounded shape. Put the layers together with icing, then use plenty of icing to smooth out and further shape the top.
A third - and easiest - method is to bake part of the cake in a rounded pan. Coffee Cans are often used for this purpose. Grease the can well or line it with parchment or waxed paper. Bake part of the cake in the coffee can, then turn it out and cool it, then cut one side off for a flat base, leaving the rounded top.

There are many alternatives to icing.
Melted chocolate thinned with a little cream.
Whipped cream and fruit.(Strawberries, in fact any berries, cherries, slices of kiwi fruit, and passion fruit are colourful.) For a special occasion dip strawberries or cherries in melted chocolate half way.
Dust the cake with sifted icing sugar, a pattern can be achieved using a paper doily.
Jam and shredded coconut.
The easiest thing to do is to get a tip for the icing bag that make a design, so you only have to squeeze the icing out but it comes out looking like a rose. Place the icing flowers scattered around the cake, or in a neat little ro along and edge or base.
