Thank you for the kind words.
Review:
.1. Good Introduction, Linkage of Urbanisation, Growing Middle class, Consumption Culture. Also you can narrow down to Tier 2 cities especially which asked in question, rather than Urbanisation as an issue as a whole.
2. Provide reasons for the growth of Tier 2 cities especially, how their growth is different from Tier1 cities.
3. Impact points are good, explore other dimensions too. Impact over Structure and Functioning of Middle class families, societies in Tier 2 cities.
4. Need to be more specific in Culture of consumption heading.
5. Good Conclusion.
Keep Writing, Keep Improving!!
