If the gator colored and with a face and eyes, you must continue to paint it or hide it. But if it is only a drawing without a face, this is permissible.

I have old lacoste shoes with a small crocodile logo on them. I tried covering the face with tape but the tape came off. I then tried covering it with permanent marker, it is now fading and the features can be seen. Shall I continue wearing them or is it not permissible?
