No problem at all. Don't worry about it. As long as the photo resembles a human, and the signature is visible, you are fine. If they find the photo and signature unsatisfactory, they'll notify you a few months later and a window will be opened for you to change them. So, no problem there.

Carry your 2 picture on exam center.

All the very best and good luck.
