Correct my choices

I'm planning to break an FD of 1lakh @ 6.6 to invest 50k in mid and small cap each as mentioned above, plus 3k SIP from monthly income in flexi for minimum 4 years. These MFs are chosen after comparing with a lot of other MFs. Factors such as expense ratio, Sharpe Ratio and past returns are taken into consideration mainly.

Kindly suggest me if I'm doing anything wrong.
