Dear Balaji,
Nice presentation. Couple of things which I would like to highlight
1) I would prefer consistency in all the slides. For eg: The boxes border is not consistent across. Width as well as height is also different. To give good visual effect, I suggest to keep it simple and same across all slides
2) Looks like in slide no: 2, the image taken is from another source. Do you have the permission to use that image?
3) Slide no's are missing.
If you can add index and contact details it would be helpful.
