A critique is honestly just your opinion on the work, also you didn’t put any pictures of the pieces of art so no one can actually answer this for you :/
Cueva de las Manos: This is obviously a very old carved image but there is just nothing in this that is really amusing to me. The only thing that attracts my attention is that someone many many years ago carved this. There is just no detail to consider this something worth art. This is more like history.
Gold Inca bird: This is a piece of art crafted with metal which is very unique and hard to create. The wings of the bird have a very cool texture and design. The only thing that is concerning is the body. This is the biggest part in this artwork and there is no design whatsoever. It is just blank and I believe if there was a design added it would be extraordinary.
To make a cake you could use a standardized recipe vanilla cake recipe. by doing this you can add just about anything you wanted by making minimal changes to the base recipe.
