According to Islam, we do not have a detailed description of 'Īsa ﷺ and none of Mariam. The brief description of 'Īsa ﷺ was given in a hadith:
حَدَّثَنَا هُدْبَةُ بْنُ خَالِدٍ، حَدَّثَنَا هَمَّامُ بْنُ يَحْيَى، عَنْ قَتَادَةَ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ آدَمَ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ: لَيْسَ بَيْنِي وَبَيْنَهُ نَبِيٌّ - يَعْنِي عِيسَى - وَإِنَّهُ نَازِلٌ فَإِذَا رَأَيْتُمُوهُ فَاعْرِفُوهُ رَجُلٌ مَرْبُوعٌ إِلَى الْحُمْرَةِ وَالْبَيَاضِ بَيْنَ مُمَصَّرَتَيْنِ كَأَنَّ رَأْسَهُ يَقْطُرُ وَإِنْ لَمْ يُصِبْهُ بَلَلٌ فَيُقَاتِلُ النَّاسَ عَلَى الإِسْلاَمِ فَيَدُقُّ الصَّلِيبَ وَيَقْتُلُ الْخِنْزِيرَ وَيَضَعُ الْجِزْيَةَ وَيُهْلِكُ اللَّهُ فِي زَمَانِهِ الْمِلَلَ كُلَّهَا إِلاَّ الإِسْلاَمَ وَيُهْلِكُ الْمَسِيحَ الدَّجَّالَ فَيَمْكُثُ فِي الأَرْضِ أَرْبَعِينَ سَنَةً ثُمَّ يُتَوَفَّى فَيُصَلِّي عَلَيْهِ الْمُسْلِمُونَ
Narrated Abu Hurayrah: The Prophet (ﷺ) said: There is no prophet between me and him, that is, Jesus (ﷺ). He will descent (to the earth). When you see him, recognize him: a man of medium height, reddish fair, wearing two light yellow garments, looking as if drops were falling down from his head though it will not be wet. He will fight the people for the cause of Islam. He will break the cross, kill swine, and abolish jizyah. Allah will perish all religions except Islam. He will destroy the Antichrist and will live on the earth for forty years and then he will die. The Muslims will pray over him.
— Sunan Abi Dawud, Book 39, Hadith 34
We, as Muslims, do not consider the depiction(s) of Jesus to be accurate or representative of how he looked like. Depictions existed at the time of the Prophet ﷺ and he did not tell his companions that 'Īsa ﷺ looked like any of them. As for Mariam, since there is no description, none of her depictions are considered accurate either.
