We have some Rabindranath Tagore criticism right here on eNotes. Please see the link below for more information.
Rabindranath Tagore, as you must have known, was quite a prolific poet. Unless you specifically mention the poems you are interested in, it is not possible to help you out. Please come back with specific titles. Tagore is a versatile poet having a long poetic career. Hope you will find his poetry very enlightening.
Rabindranath Tagore has written many poems. The most well known collection of his poems is Gitanjali, for which he received a Nobel Price in literature in 1913. I am not sure, how many different poems by Rabindranath you need for your analysis. I am reproducing below one of his very popular poem written in English.
Let My Country Awake
Where the mind is without fear and the head is held high;
Where knowledge is free;
Where the world has not been broken up into fragments by narrow domestic walls;
Where the words come out from the depth of truth;
Where tireless striving stretches its arms towards perfection;
Where the clear stream of reason has not lost its way into the dreary desert sand of dead habit;
Where the mind is led forward by thee into ever-widening thought and action -
Into that heaven of freedom, my Father, let my country awake.
