I'd say likeness is first God's qualities - Kind, Good, Loving, Faithful, Perfect(without sin/sin nature), and so on. The physical image is what we are now as human. Now here's the thing. If God is omniscient then God knew what was going to happen 'long before' everything got created. From the Fall to what The Son(aka Jesus Christ) had to do. So being human like we are is not surprising because God already knew what we'd look like.
Now here's the interesting part. The Son is perhaps the most unique singular individual in the whole of creation. We humans are less than 100% human at the moment because of the sin nature. The Father and Holy Spirt are 100% God.
The Son who is also 100% God became 100% Human(no sinning, no sin nature). Sure He could have come to Earth as 100% God but in that 'form', whatever that might have been, however He could have not have satisfied the sin price(shedding of blood, death). So He became 100% Human on top of being 100% God. 100% Human so the sin price could be paid in full for not only the 'present' of His time on Earth but those who believed under the Old Covenant(Moses, David, Adam, Eve, Deborah, Job, etc, etc) but up to the present and far into the future until it's all said and done.
Now such an act on top of being able to handle all the suffering and torture that lead up to the cross and 'taking in of' the unknowable number of sins of the unownable number of believers (for us humans we don't know the actual numbers) would take a literal act of God to pull off. In that case Jesus would have to have retained His Divinity or Godliness as The Son. Or as Jesus put it - "With man it is impossible. With God all things are possible."
So did Jesus 'shed' the Human side when He returned to Heaven to sit beside His Father? NO! It's heavily implied in Revelation that Jesus is still 100% Human/100% God. This is shown by verses that describe Him with having 'pure white hair and beard'. Some have even theorized that Jesus still retains the scars caused by the nails and being stabbed by that spear.(He was already dead when stabbed). This is because He showed Thomas the scars as proof of who He was.
Again it does not matter what physical form we were created as because the Godhead/Trinity already knew what was going to happen from beginning to end and the huge part of that was The Son taking the form of a physical Human.
