An idol problem.

[jas3]

If I kept it as a momento for what Jesus did for us than yes its an idol because it's a graven image of a figure of Jesus Christ and it is not what God looked like when he died on the cross for us. It's impossible to carve an image of God that accurately portrays God's full Glory and God's full image because nobody knows what God truly looks like and nobody can accurately portray him and that's why idols are forbidden.

I'm sure his advice was well-intentioned, but this is not compatible with Jesus Christ actually being God.
