Hi,

I hope you are doing well.

No, absolutely not it wouldn’t look bad on your resume.

It is quite common to change streams and line and pursue something of your interest where you realise your skills can be developed and be helpful in the real world.

So, don’t worry about anything much & chose a pathway which interests you and where you are sure you can perform very well and ace it & if asked a reason for the change of stream, you could always provide a strong reason for it & people do understand it.

So, yes it wouldn’t look bad on your resume.

I hope the above information helps.
All the very best.
